 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...

  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

 There are mainly five types of load, which are considered while designing a steel structure. They are - Dead loads, live/imposed load, wind load, snow load and earthquake load. In this article, a brief introduction of different types of load is given. Dead load (DL) It is the self - weight of structure. It is calculated by volume of each section multiplied with unit weight. Complete details of dead loads is given in IS:875(part-I)-1987. Live/imposed load (LL or IL) It varies in magnitude and in positions. It is applied on the structure temporarily. It depends on the intended use of the building. Related to IS:875(part-II)-1987. Wind load (WL) It is the horizontal load caused by movement of air relative to the earth. Essential to consider when the height of building exceeds two times the dimensions transverse to exposal wind surface. Depends upon velocity of wind and size of building. Related to IS:875(part-III)-1987. Snow load (SL) Vertical loads in the building. Considered only i...
