CEMENT HARDENING INHIBITION COMPONENT ADSORBING MATERIAL AND METHOD OF PRODUCING CEMENT HARDENED BODY USING THE SAME CEMENT HARDENING INHIBITION COMPONENT ADSORBING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a cement hardening inhibition component adsorbing material for adsorbing a cement hardening inhibition component to suppress the hardening inhibition to rapidly carry out the hardening of cement by the hydration reaction even if the hardening inhibition component inhibiting and retarding the hardening of the cement is incorporated, and a method of producing a cement hardened body while suppressing the hardening inhibition of the cement by adding the hardening inhibition component adsorbing material in which the treatment work for suppressing the hardening inhibition is simplified by the addition of the hardening inhibition component adsorbing material without causing various problems by the use of a conventional cleaning method, a means for applying a wooden reinforcing material, a method of using a hardening promotion agent or the like.

SOLUTION: The cement hardening inhibition component adsorbing material adsorbing the hardening inhibition component is incorporated in a cement composition containing cement and a hardening inhibition component-containing material containing hardening inhibition component inhibiting the hardening of the cement and contains calcium silicate hydrate having≥30 m2/g BET specific surface area and a molar ratio Ca/Si of 1.2-4.0.
