Abstract
An early strength enhancer for hydraulic compositions contains calcite with a crystallite size in the (104) plane calculated by the Scherrer equation of 30 nm or less and improves the strength of hardened products of hydraulic compositions after, for example, 5 to 20 hours from preparation. A hydraulic composition contains the calcite, a hydraulic powder, and water. A method for producing the hydraulic composition includes a step of mixing the calcite, the hydraulic powder, and water.
