General Description
Metakaolin is a highly reactive pozzolan composed of amorphous aluminosilicate materials that is produced by calcining kaolin clay at high temperatures. It is primarily used as a supplementary cementitious material in concrete production to improve strength, durability, and workability. Metakaolin reacts with the calcium hydroxide in cement to form additional calcium silicate hydrate (C-S-H) gel, which enhances the overall performance of the concrete. This supplementary material also reduces the production of calcium hydroxide and lowers the porosity of the concrete, resulting in a denser and more durable structure. Metakaolin can also be used in the production of high-performance concrete, as well as in grouts, mortars, and other construction applications. Its pozzolanic properties make it an environmentally friendly and sustainable alternative to traditional cementitious materials.Check Digit Verification of cas no
The CAS Registry Mumber 15123-81-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,2 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 15123-81:
(7*1)+(6*5)+(5*1)+(4*2)+(3*3)+(2*8)+(1*1)=76
76 % 10 = 6
So 15123-81-6 is a valid CAS Registry Number.
