HSA Microsilica

The composite silicate heat insulation coating containing micro silica fume is mainly used as industrial thermal insulation coating, such as high temperature pipeline insulation, or boiler, kiln and other shell insulation, concentrated in power, chemical industry and other industries. 1. The application of the power industry Thermal insulation plays an important role in power plants, […]

High-strength non-shrinkage grouting material (non-shrinkage cement, super-early-strength grouting material, high-strength non-shrink grouting material, cement mortar reinforcement material, cement-based grouting material) is made of high-strength material as aggregate and cement as the base material, supplemented by High fluidity, micro-expansion, anti-segregation and other substances are formulated without iron ion and chlorine salt; early strength, high strength, micro

Various types of concrete construction requires different concrete indexs for its construction. The recommended value of these concrete mixes for various types of construction is presented in table below: Type of work Concrete Mix Ratio Max. size of aggregates (mm) Water for dry aggregates (liter)* Water for aggregates condition from dry to moist batch (liter)* Water for

The concrete is manufactured using cement, sand, gravel and water as the main components materials. The active material in concrete is cement which binds other materials physically and chemically with water and solidifies. Sometimes admixtures are used in concrete to enhance its properties. 1. Cement There are various types of cements used for manufacture of

Supplementary Cementitious Materials (SCM) are added to concrete mixtures for various reasons including improving durability, decreasing permeability, aiding in pumpability and finishability, mitigating alkali reactivity and improving the overall hardened properties of concrete through hydraulic or pozzolanic activity or both. SCM are added to concrete in addition to or as a partial replacement of Portland

Quality tests on cements at construction site (also called field tests on cement) are carried to know the quality of cement supplied at site. It gives some idea about cement quality based on colour, touch and feel and other tests. The following are the quality tests on cement at construction site: – Color test –

Microsilica can be used in gypsum products as a process aid, to improve ingredient dispersion and to improve hardened properties and overall durability, particularly in fire tests. Microsilica Grade 920 is a dry silica fume available in two main forms: Undensified (U) and Densified (D). Microsilica Grade 920 is a dry silica fume available in
