Chemical analysis of Building Materials

Chemical analysis of building materials plays a very crucial role so as to identify every ingredient of the constituent material. The chemical analysis of materials also help us estimate the physical behaviour upto an extent. Our experts analysis with acute precision with our advanced analytical equipments to analyse every constituent of the sample. The analysis are carried out with care and maintained laboratory atmosphere.

Cement composition involves both major and minor oxides. The major oxides include CaO, SiO2, Al2O3, and Fe2O3 whereas the minor oxides also include MgO, SO3, and some alkali oxides (K2O and Na2O) and sometimes the inclusion of other compounds, P2O5, Cl, TiO2, MnO3, and so forth. Each of the oxides performs unique work during cement hydration; however, each content of the oxide must be in the right quantity during proportioning of raw materials.

GGBS typical chemical composition contains calcium oxide 40%, silica 35%, alumina 13% and magnesia 8%. The glass content of slag’s suitable for blending with Portland cement typically varies between 90-100% and depends on the cooling methods.

Admixture is a material other than water, aggregates, or cement which is used as an ingredient of concrete to alter the properties of concrete therefore it is necessary to carry out analysis of admixture. Analysis are carried out for dry material content, pH, Relative density, Chlorides as it directly effects concrete.

Flyash is a fine powder that is a byproduct of burning pulverized coal in electric generation power plants. Fly ash is a pozzolonic substance containing aluminous and siliceous material that forms cement like paste in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement. It helps in reduction of cement content in concrete mix. It is analysed for silicon dioxide (SiO2), aluminium oxide (Al2O3) and calcium oxide (CaO).

Silica fume is a by-product of producing silicon metal or ferrosilicon alloys. One of the most beneficial uses for silica fume is in concrete and used as mineral admixture. Because of its chemical and physical properties, it is a very reactive pozzolan. Concrete containing silica fume can have very high strength and can be very durable.

Water is one of the most important elements in construction and is required for the preparation of mortar, mixing of cement concrete and for curing work etc. The quality of water used has a direct impact on the strength of the motor and cement concrete in the construction work.
