 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

  PVC - Polyvinyl chloride It is a vinyl polymer which structure is very much similar to polythene. It is produced by the free radial polymerization of vinyl chloride. In the recent years, the use of polyvinyl chloride has been increase in construction work due to their excellent property. It is resistance to fire, water, flame, and corrosion. It has light weight and great insulating property. As a building material, PVC is cheap and easy to assemble. It has become an alternative of conventional building materials like wood, concrete or clay. Advantages of PVC - Being a resistance to water, it is used to make shower curtains, water pipes etc. Being a hard plastics, it is used in window profiles, pipe, plumbing etc. It is extensively used in sewer industries for pipelines of the water. It is flexible. After addition of plasticizers, we can use it as roofing membranes and in electric cable insulation.  Thank you. Gracious! My Quora space My YouTube channel
