Carbonatation
Carbonatation is a slow process that occurs in concrete where lime ( CaO, or Ca (OH) 2( aq)) in the cement reacts with carbon dioxide (CO 2) from the air and forms calcium carbonate The water in the pores of Portland cement concrete is normally alkaline with a pH in the range of 125 to 135 This highly alkaline environment is one in whichPrecipitated Calcium Carbonate PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3 The calcium, carbon and oxygen atoms can arrange themselves in three different ways,Precipitated Calcium Carbonate Minerals Technologies Inc
