In the most general sense of the term, a concrete is a substance that solidifies to act as a glue. The Romans were the first to use "modern cement" for walls made of crushed stone with quicklime as a binder. They called this substance “cementicium opus”, which was later called cement, cimentim, cäment and cement. Cement is mainly used in construction. It is a gray, powdery substance made from lime and baked clay, mixed with water and sand to produce mortar (a paste used to join bricks together and fill the spaces between them) or with water, sand and gravel to produce concrete (a strong and durable material). building material). The cement industry is of critical importance in today's highly dynamic and developing world. To initiate, sustain and sustain growth, it is imperative that a country's cement industry operates efficiently, effectively and, above all, productively. For a developing country like Pakistan, the amount of cement production used per person indicates the stage of development. Analysts and experts believe that the demand for cement is directly proportional to the level of economic, demographic and urban growth. Furthermore, demand is directly related to the level of construction activities and corresponding activities occurring across the country. The history of the cement industry in Pakistan dates back to 1921, when the first plant was established in Wah. When Pakistan became independent, it inherited four cement industries operating with an installed capacity of 470,000 tonnes per annum. Karachi, Rohri, Dandot and Wah were among the citations. The number of concrete units rose to six in the decade 1948-1958. Since then, Pakistan's cement industry has changed and has undergone a paper-based, non-hydraulic process. Different types of cement used can produce different amounts of gypsum, clinker and other additives, but only certain types of cement are commonly used today due to cost and binding power. Non-Hydraulic Cement Hydraulic cement is the cement that cannot harden while in contact with water, compared to the can of hydraulic cement. When non-hydraulic cement is used in construction, it must be kept dry so that the structure is maintained. Due to the difficulties involved in waiting, it is rarely used in today's market.Hydraulic cementHydraulic cement is a cement that has fixative capacity and hardens after being combined with water. Hydraulic cement is mainly made of limestone, some clay minerals and gypsum, which are burned together at high temperature. Hydraulic cement is the cement used in major construction today.
