BAIJIAN - Third party testing organization
Concrete admixtures are used to improve the performance of concrete、 save water、 adjust the strength grade of concrete、 and add natural or artificial powdered minerals that can improve the performance of concrete during concrete mixing. Admixtures can be divided into active and non active admixtures. The active mineral admixture itself does not harden or hardens slowly、 but can be mixed with calcium materials such as lime and hydrated lime with water. It can solidify and harden to produce strength、 or react with calcium hydroxide generated by cement hydration to generate hydration products with cementing ability、 such as fly ash、 granulated blast furnace slag powder、 zeolite powder、 silica fume、 etc. Non active mineral admixtures refer to mineral admixtures that are mainly used for filling in cement without damaging its performance. Non active admixtures do not react with cement components、 such as limestone、 ground quartz sand、 and other materials. Commonly used concrete admixtures include fly ash、 granulated blast furnace slag、 and volcanic ash. Especially fly ash、 ultra-fine grained electric furnace slag、 and silica fume have good application effects
