The concrete maintenance process is very easy and the maintenance cost is low. 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. 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%. ~ Water having a pH value less than 6 is not suitable for use in plain cement concrete. It includes mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibers. No corrugations are developed in cement concrete roads. This makes it the perfect material for ground floor layers and providing a stable and even base for reinforced concrete to be built onto while limiting its use in larger construction projects. Concrete is a long-lasting material. 13. If steel is kept in the concrete then it is called Reinforced cement concrete (RCC). 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. However, when placed under tension it is much weaker and can often crack and buckle. PCC with grade M-30, M-40 and M-45 were utilized at the construction site with several design mix. Reinforced Cement Concrete (RCC) Mixture of cement , sand and coarse aggregate with reinforcement is known as RCC. Made from a mix of cement, aggregate, and water the different types of aggregate and ratio of materials used will give different types of cement with slightly different properties. All the cement used in Hong Kong is imported, much of it as clinker which requires a considerable amount of energy to grind. Advantages of Concrete The following are the advantages of concrete Concrete ingredients are easily available. The quantity of calcium chloride is limited in a concrete mix is about 1%-2% by weight of cement. Advantages of Reinforced Concrete Reinforced concrete has a high compressive strength compared to other building materials. Advantages of PQC.
