What is Impact of Insoluble Residue on Cement about?
The document discusses a study on the effect of insoluble residue on the properties of Portland cement. Finely crushed sand was used as artificial insoluble residue and replaced Portland cement in amounts from 0% to 7% by weight. The results showed that insoluble residue did not affect cement setting times but did reduce compressive strength, especially at early ages. However, the strength reduction was less than 5.5% even with 7% insoluble residue, suggesting the ASTM limit of 0.75% could be increased with
