Efflorescence inhibitor for ordinary Portland cement
The invention relates to an efflorescence inhibitor for ordinary Portland cement. The efflorescence inhibitor comprises the following raw materials in parts by weight: 5-10 parts of sulphoaluminate cement; 35-45 parts of mineral powder; 5-10 parts of metakaolin; 5-10 parts of silica fume; 1-2 parts of active white carbon black; 1-3 parts of latex powder; 0.1-0.3 parts of cellulose ether; and 0.05-0.15 parts of starch ether. According to the present invention, the efflorescence degree value, the calcium hydroxide content and the compressive strength value of a test piece using the efflorescenceinhibitor at each stage can be determined through a specified method, the performance of the efflorescence inhibitor can be quantitatively evaluated, and the early efflorescence degree and the secondary efflorescence degree can be effectively reduced; and the compactness of cement is improved, early shrinkage is reduced, and later compressive strength of the test piece is improved.
本发明涉及一种普通硅酸盐水泥的泛碱抑制剂。本发明包括如下重量份的原料：硫铝酸盐水泥：5‑10份；矿粉：35‑45份；偏高岭土：5‑10份；硅灰：5‑10份；活性白炭黑：1‑2份；乳胶粉：1‑3份；纤维素醚：0.1‑0.3份；淀粉醚：0.05‑0.15份，本发明能通过规定的方法去测定使用所述泛碱抑制剂后的试件的各阶段泛碱程度值、氢氧化钙含量和抗压强度值，定量评价所述泛碱抑制剂的性能，本发明能有效降低早期泛碱程度以及二次泛碱程度；提高水泥的致密性，降低早期收缩，提高试件后期抗压强度。
