Water is added in the necessary quantities and the mixture is arranged into a mechanical mixer to obtain concrete. 7. Every example of concrete construction will require both plain and reinforced concrete and hopefully, this article will help you recognise the difference and make the right choice for your project. A concrete without reinforcement steel is called Plain Cement Concrete (PCC). With the concrete maintaining its strength under compression and the steel resisting any bending or stretching thanks to its tensile strength the RCC is a much more versatile construction material. The product became popular because it … PCC is strong in compression and week in tension. However, the successful outcome of any floor–be it normal concrete or lightweight concrete–is determined by taking into account the different concrete curing processes to reduce the risk of floor failures. If steel is kept in the concrete then it is called Reinforced cement concrete (RCC). The PCC should have high compressive strength. The shrinkage of cement concrete happens when it gets solidified. Concrete = • 25-40% cement (absolute volume of cement = 7-15% … design of plain jointed cement concrete pavement, » More detailed advancement in reinforced concrete as a material ppt Since the first strip of concrete pavement was completed in 1893, concrete has been used extensively for paving highways and airports as well as business and residential streets. Plain Cement Concrete (PCC) is a construction material generally used as a binding materials and is composed of cement, (commonly Portland Cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravels or crushed rocks such as limestone or granite, plus a fine aggregate such as sand), water, and chemical admixtures. It is formed by mixing the basic components like cement, fine aggregate (generally sand) and coarse aggregate (generally stone pieces) in desired ratios. Plain or lightly reinforced concrete can be used in the form of precast shell roofing. 1. Plain cement concrete is high in compression and very low in tension. 3: Aids, cold weather concreting. This combination is made to utilize the compressive strength of concrete and tensile strength of steel simultaneously. Economical Save. Unlike natural stones, concrete is free from defects and flaws. Advantages Of Cement Concrete Road. Every ingredient of concrete consists different properties so, it is not an easy task to get economical and good concrete mix. Plain transverse section before bending remains plain after bending. Concrete roads have a long life. Crusher Products Steel is the most common material used for the creation of rebar as it reacts to very similar variances in temperature as concrete, meaning it will expand and contract with the concrete rather than cracking it from the inside. iii) Simple construction. Advantages of Concrete The following are the advantages of concrete Concrete ingredients are easily available. Disadvantages Of Concrete Design 1318 Words | 6 Pages. Advantages of PQC.

Concrete sets, hardens, gain its strength at regular room temperature … This is one of the main selling points of ready mix concrete as the exact values and types of aggregate can be measured and monitored precisely to provide the qualities that are needed without any variance. Reinforced concrete is a combination of traditional cement concrete with reinforcements (steel bar). It reduces CO 2; Green concrete reduces environmental pollution. Properties of Plain Cement Concrete(PCC) Some of the properties of plain cement concrete are: a. All tensile stresses are taken up by steel reinforcement only and the resistance of concrete to tension is nil. However, when placed under tension it is much weaker and can often crack and buckle. The durability of concrete is very high. 9. Plain Cement Concrete or PCC stands for a composite material that is applied for building up different types of civil engineering structures. Production of structural steel demands 8000 kWh/ton or more to make, which is almost 3-10 times the energy consumption. 2. PCC is mainly used for following purposes: 1- It is used as a protective layer for the RCC above so that water from the RCC is not absorbed by the earth below. Concrete ingredients are easily available. 1. Concrete is a long-lasting material. ALSO READ: DIFFERENCE BETWEEN CONCRETE AND CEMENT. Strength. Without quality control, there is no guarantee that the weakness of one area will be compensated in another by over spending in that area. A concrete becomes functional when it is blended easily, managed, transported, arranged in position and compacted. All the cement used in Hong Kong is imported, much of it as clinker which requires a considerable amount of energy to grind. In comparison with the plain cement mortar, the addition of 0.1% concentration of MWCNTs increased the compression strength by 56%, whereas concentrations of 0.1% of HNTs increased by 31%. For plain cement concrete, only 450–750 kWh/ton energy is required and that of reinforced concrete is 800–3200 kWh/ton. They provide an impervious, dustless and sanitary surface. Conversely, with the age, the concrete gets hardened and as a result, the strength is greatly increased. The types and advantages of concrete mix design are discussed […] Staining imparts a luxurious richness that can’t be achieved by any other coloring medium. 3. in the concrete. Thus cement concrete can be prepared by mixing above ingredients in a fixed pro­portion. Er. Concrete is a mixture of water and cement powder. Concrete block homes don’t always have curb appeal. 11. It is incredibly strong under compression whilst weak under tension, this means that when on a solid, unmoving surface it is capable of withstanding huge amounts of weight. For plain cement concrete, only 450–750 kWh/ton energy is required and that of reinforced concrete is 800–3200 kWh/ton. Location Map, Product Data Sheets Advantages of Concrete Ingredients of concrete are easily available in most of the places. The Concrete fairly acts as thermal insulation. A suitable frame is made to cast the shell unit. They provide an excellent riding surface under all weather condition. In reinforced concrete, the components work together to resist many types of loading. 12. Plain concrete, also known as plain cement concrete or PCC, is most commonly used for paving and flooring. It has better adjustment to sub-grade changes and possibility to use slightly poorer quality of aggregate. It Reduces the permeability. The automated manufacturing process limits the potential of human error while saving time and resources. The following are the advantages of concrete. Design mixes commonly used for PCC are 1:4:8 , 1:3:5 , 1:2:4 , M7.5, M10 etc. stands for Reinforced Cement Concrete, and now a days is the main Constructional Material which is used to construct different structural parts, by using R.C.C. P.O. Prev Article Next Article . Able to stand up to weight pushing down onto it as well as any wind pressure or shifting that results in slight twists and strains thanks to the increased flexural capacity of the concrete/steel mix, it is the ideal material for taller and heavier buildings and for roads and bridges. Last Updated on October 9, 2019. 4. Workability is the most subtle properly of concrete. PCC with grade M-30, M-40 and M-45 were utilized at the construction site with several design mix. Fiber Reinforced Concrete can be defined as a composite material consisting of mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibers. Concrete is homogenous and elastic. The concrete maintenance process is very easy and the maintenance cost is low. Cement, a main component of concrete, is one of the world’s biggest contributors to greenhouse gas emissions. It includes mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibers. When tensile stresses are developed, it cracks. It had been using in many countries. Disadvantages of Superplasticizer: 1. 2.2 Characteristics on Glass Fibre Reinforced Concrete (GFRC) Glass fibre reinforced concrete is defined as a concrete composition that consist material such as cement, sand, water and admixtures with short length discrete glass fibre were dispersed (Amit Rai et al,2014). As society has progressed, so too have the building materials we use and that has led to quite a bit of variety in term of the types of concrete we now have available. No corrugations are developed in cement concrete roads. By casting the wet cement around reinforcing steel bars the resultant composite material has much more strength under tension while still keeping the properties that make PCC so effective. Below we’ll lay out the positives and negatives to both types of concrete to help you make the right choice for your needs. The agglomeration of the nanoparticles was also observed in MWCNTs, which led to the concept of using lower concentration. Some are given below: Plain Cement Concrete. 6. Also in plain cement concrete is a chance of brittle fracture because of the propagation of micro-cracks present in the concrete that makes poor tensile strength. Plain cement concrete is a hardened mass obtained from a mixture of cement, sand, gravel, and water in definite proportion. Plain Concrete. 13. All the cement used in Hong Kong is imported, much of it as clinker which requires a considerable amount of energy to grind. Management While there are differences in the composition of the concrete most plain concrete shares the same strengths and weaknesses. Green concrete has many advantages over conventional concrete such as: Green concrete uses local and recycled materials like fly ash, GGBS (Ground Granulated Blast Furnace Slag, artificial aggregates etc. Cement concrete is an important construction material. Merits/Demerits of Concrete pipes: Advantages:-Fire and weather resistance. Hence PCC is used only in places/members when tensile loads are not acting on it, i.e., only compressive loads are acting. Fax Number: +973 17 591 267, Artificial Stone The concrete experiences an extra strain apart from momentary pressure due to a load or stress. At Al Manaratain we pride ourselves on the quality of the concrete blocks, concrete pavers, precast concrete, and ready-mix concrete products we have to offer. Concrete structure can be made with many different ways. The compressive strength of concrete is influenced by the following factors :-. The tensile strength should be 8-12% of compressive strength and shear strength should be 8-10% of compressive strength. The direct economic benefits deriving from the use of PFA as fill are small compared with its use as a cement replacement in concrete. PQC is used as a Top layer of Cement concrete road. Advantages of Reinforced Concrete Reinforced concrete has a high compressive strength compared to other building materials. Fiber-reinforced concrete is used to overcome the difficulty of plain cement concrete which gives very low tensile strength, low ductility strength, and a little strength to cracking. It has good thermal resistance and acid resistance. ... Cement concrete is poured and manually compacted. They are quite durable and practically unaffected by weathering agencies. iv) Free from corrosion due to the absence of steel. Al Manaratain Micro voids in concrete will be densified and refined to provide neat concrete microstructure , . b. It has been possible to upgrade the qualities of cement by using high-quality limestone, modern equipment, closer on line control of constituents, maintaining better particle size distribution, finer grinding and better packing.
