   Now a days, the use of  Ready Mix Concrete (RMC) in large construction work has been continuously increasing. RMC is a concrete that is scientifically manufactured in batching plant and transported to the site by transit mixer without affecting its fresh properties.   The transit mixer is of two types - In one type, dry concrete is made at the batching plant, loaded into agitator truck mixer and water is added during transportation. Thus wet concrete is formed. In the other type, mixed wet concrete is made at the batching plant discharged into the agitator truck mixers and transported to the site. The drum in concrete is made to rotate till the concrete is placed to keep the concrete in plastic state. Procedure  The raw materials are tested in the plant before its use to ensure compliance with relevant standards. This eliminates the possibility of quality problems in the end product. The aggregates of different sizes are stored in separate bins and mixed in desired proportions to ge

 PCC - Plain Cement Concrete PCC is the concrete which is simply containing cement, sand, aggregates and water in suitable proportions. There are no reinforcement is provided in this type of concrete. It has much compressive strength than tensile strength. Practically, It has been observed that it is very weak in tension. Material used in PCC Cement - We can use any type of cement in PCC but Portland Pozzolona Cement is more common and suitable. Sand - It should be hard, durable, strong, clean and well - graded. Aggregates - They also should be hard, durable, strong and well graded. Fine aggregates act as fillers and coarse aggregates provide strength to the concrete. Water - It should be potable i.e. it should be clean and free from injurious amounts of acids, alkalis, salts etc. The hardening of concrete is taking place due to chemical reaction between cement and water. Properties of PCC  Uses of PCC  As a base for RCC foundation, ground floor and load bearing walls. As DPC at plinth
