What Is The Difference Between Concrete Blocks And Cinder Blocks? The primary difference between concrete blocks and cinder blocks lies in their construction; cinder blocks are hollow rectangle-shaped structures usually made of concrete and coal cinders that find use in construction sites, while concrete blocks are flattened constructs made of steel, wood, or cement. Cinder […]
What Is Guniting In Construction? Guniting in construction is a process of spraying concrete or mortar using guniting machines. It typically involves a pressurised tank containing the material, and a turbine powered nozzle attached to a hose which sprays the material on the surface being treated. This process helps to close up gaps between panels, […]
What Is Carburizing Hardening? Carburizing hardening is a thermochemical process used to strengthen metals by introducing carbon atoms into the surface layer of the material. The process involves heating the part up to a temperature high enough for liquid or gaseous carburizing agents, such as carbon monoxide or acetylene, to diffuse into it and react […]
What Is Cement Kiln? Cement kiln is a kind of large-scale industrial equipment for calcining cement clinker. It consists of the cylinder, preheater, suspension preheater, and kiln body. The rotary kiln has high production capability and strong adaptability to raw materials, fuel and product types; it can be widely used in various building materials, metallurgy, […]
What Is Meant By Thermal Expansion? Thermal expansion is a phenomenon that occurs when the temperature of an object increases, which causes its matter to expand in shape, volume and area. This is due to the increase in kinetic energy of the molecules within it. As they gain more energy, they vibrate more rapidly and […]
What Is Cement Milling? Cement milling is the process of grinding together cement clinker, gypsum and other additives to produce a fine grey powder. The resulting material, called “cement meal”, is then heated in a rotary kiln to around 2,000°F to produce the finished product known as Portland cement, which can be used for many […]
What Is Alkali-Silica Reaction In Concrete? Alkali-silica reaction (ASR) is an expansive chemical reaction occurring in concrete between alkalis present in the cement and silica present in the aggregates. This reaction results in a gel-like substance, referred to as “ASR gel”, which absorbs water from the environment, swells, and exerts pressure on both hardened and […]
What Is A Cement Rendering? Cement rendering is the process of applying a mixture of cement, sand, and lime to brick, concrete, stone, or mud brick walls. It is a cost-effective way to improve the appearance and weather resistance of exterior walls and can be textured, colored, or painted after application. This technique has been […]
What Is A Enviroboard in Constructions Enviroboard is a construction and packaging material made from compressed agricultural waste such as rice straw, wheat straw, and elephant grass. It can also be made from urban waste like newspaper fiber. It has been used for hundreds of years, especially in Eastern and Central Europe, as insulation and […]
What Is Cement Clinker? Cement clinker is a solid material made during the production of Portland cement. It is formed by heating a mixture of raw materials, including limestone and clay, to high temperatures in a kiln. The resulting clinker consists mainly of four minerals: alite, belite, tricalcium aluminate and calcium aluminoferrite. These minerals are […]
