Pozzolana and Cement’s Secret

Natural or artificial contains mainly active silicon oxide, activated alumina mineral material, after the ground into a fine powder mixed with lime water, not only can in air hardening, and can continue to hardening in the water, are called Pozzolana hybrid materials. Pozzolana mass mixing materials is a kind of active mixing materials, it can be a composite Portland Cement, made Pozzolana Cement. Due to the pozzolanic cement clinker is relatively reduced, cement hydration speed and low hydration heat, but the total number of calcium silicate gel than Portland cement hydration, so the late strength have bigger growth. In addition, the ordinary cement in case of water deficiency in the process of hydration, make the Ca(OH)2 has long been the effect of CO2 and generate CaCO3, will make the cement hydrates decomposition and destroying the structure of cement stone. This kind of cement surface frost, atmospheric stability is poorer, and after mixed with Pozzolana qualitative material, can make the cement has good corrosion resistance to dissolution.

Pozzolana Cement Production Line

Pozzolana Cement hydration, setting and hardening process is mainly the clinker hydration and mixed material associated with the reaction of Ca(OH)2. Pozzolana Cement after adding water, the first is the hydration of Portland Cement clinker, generate the Ca(OH)2, become mixed with pozzolanic materials produce secondary hydration reaction of exciting agent; The activity of pozzolanic admixture in the highly fragmented oxide absorption of Ca (OH) 2, and then by the reaction with hydrated calcium silicate as the main body of the hydration products, namely, hydrated calcium silicate gel and hydration of calcium aluminate gel. In fact, Pozzolana Cement hydration reaction is twice alternate, and condition each other, restrict each other, and is not a simple isolated. Such as: due to the secondary reaction, to a certain extent, consumes clinker of hydration products, namely, the liquid phase of Ca (OH) 2 and active SiO2 and Al2O3 secondary hydration reaction, formation of hydrated calcium silicate, and hydrated calcium aluminate, thus reduce its concentration (alkalinity lower), as a result, which in turn prompted clinker mineral continue hydration, so repeated, until the reaction completely.

How to Make Pozzolana?

Pozzolana Cement because of its good stability and good resistance to dissolution of the corrosion is very popular in the market, and Pozzolana Pozzolana Cement production and has a great influence, so Pozzolana want how to make? First should choose to contain active silica and activated alumina ore, such as basalt, through its crusher broken into pieces, and then through the mill grinding, Pozzolana. Process wouldn’t be so simple, of course, the specific machine model choice and the collocation of production line is to be combined with the actual production of the mine, if you have a mine, and at the right moment to make Pozzolana, then Contact Us, we will help you create a favourite Pozzolana Cement: Supplier like Pozzolana, Just Contact Us!
