Cement additive and cement composition |
| abstract |
(57) [Summary] (Problem corrected) [PROBLEMS] To provide an additive for cement showing a quick setting property and the development of compressive strength in a short time with a small amount of addition, and a cement composition using the additive. The cement additive is an intramolecular dehydrate of a polyhydric alcohol represented by the formula (1), erythritol. (Where n is an integer of 2 to 4) and the cement additive (A), cement, water, aggregate, and water reducing agent (B) And the cement additive (A) contains 0.1% of cement. -15% by mass, and the water reducing agent (B) is 0.1% of cement. A cement composition which is 0.5 to 5% by mass. |
