Metakaolin HRM White Kaolin Clay Price

Product Description

TZJ CM is a specially designed high-reactivity tephros or metakaolin (HRM) for architectural concrete. It features proper particle size. TZJ CM can significantly improve early and later strength of Portland cements and special cements.

Application information

When mixed with ordinary Portland cement, TZJ CM can react with Ca(OH)2 precipitated from the mixture and prevent the alkali aggregate reaction as well as formation of cracks. Meanwhile TZJ CM fills the pore space between cement and sand, reduce formation of cement pores and therefore improve early and later strength of cements. Recommended dosage is 5-20% by dry weight of cement, generally 10%.

TZJ CM is widely used in cast-in-place and precast concrete, glass fiber reinforced concrete (GFRC or GRC), mortars, grouts, and other cement-based products.
