Brief introduction of metal powder

Study from the choice of substances,Guest Posting creation strategies and pouring conservation and different aspects of the unique requirements of the silicon powder concrete production. Engineering examples prove that the silicon powder concrete hydraulic systems with superior overall performance than ordinary concrete.

Silicon powder is ferroalloy smelting retumbo smokeless powder generated by means of high purity quartz and coke chemical reaction in electric arc furnace, and obtained by using accumulating emissions of fuel powder in the electric arc furnace. 1982 steel powder dealer first time introduced silicon powder into concrete and comprehensive observe of its performance, silicon powder concrete purpose humans’s issues. Due to the complementary residences of silicon powder concrete and Portland cement, coupled with the benefit of environmental protection (silicon powder with the electric arc furnace gasoline into the air, causing extreme dirt pollution), silicon powder has been recognized as a brand new auxiliary cementing cloth being broadly studied and carried out.

Adding silicon powder can efficiently reduce the accumulation of moisture in concrete and steel interface, to improve the adhesion of reinforced concrete. Under the identical conditions of the water-cement ratio and concrete blend share, the compressive strength of blend silicon powder concrete become drastically better than regular concrete. Experimental research have proven that greater than 20% silicon powder dosage in concrete, the compressive strength of silicon powder concrete not growth with increasing silicon powder dosage; silicon powder dosage does now not exceed 20%, the elastic modulus of the silicon powder concrete is multiplied with the silicon powder content material expanded.

Silicon powderaverage particle length is a hundred mm, belong to the case of nano-particles, with advanced overall performance of the volcanic ash. Added to cement concrete, no longer handiest can fill the voids of the cement, extra important is the nanometer silicon powder react with Ca (OH) 2 in the cement paste, generated colloidal hydrated calcium silicate, improve the interface of cement paste and aggregates shape and overall performance. Reduce porosity, greater the concrete impermeability and durability. The look at showed that the silicon powder concrete can successfully withstand the CL-penetration, and greatly reduce the corrosion of bolstered concrete CL-invasive Shun tendons cracks, for you to effectively enhance the performance of concrete cracking. This superiority is particularly appropriate for a harbor concrete engineering.

Due to the silicon powder special bodily and chemical properties, may be used in production high-strength, low permeability and chemical resistance of concrete, in hydraulic structures, transportation, building production all have a big market. But silicon powder concrete construction technology and regular concrete isn’t the equal, handiest to strictly study and accurate use of silicon powder concrete merchandise will get qualified.

Silicon powder in the delivery and storage should be kept dry and now not damp. For ease of use, silicon powder can mechanical agitation into a uniform slurry awareness of 30% to reserve seven days before use. The stored slurry pond need to be clean and watertight, protected to avoid evaporation and to save you the influx of rain and sewage. Before construction, to save you sediment stratification should be stirring frequently to make sure uniformity. Silicon powder concrete droop is sensitive to the quantity of water added. The moisture content material have to be measured before creation, aggregate creation website and calculate concrete design water, components to prevent agglomeration, pleasant made answer Stir before the use of. Silicon powder concrete as a floor layer with ordinary concrete pouring, earlier than the initial setting normal concrete vibrators laid silicon powder concrete, and used pokers inserted ordinary concrete layer 2 cm vibration compacting, assure higher concrete bonding between layers.
