山西省建筑科学研究所建材室最近研制成功高效复合早强抗冻减水剂 SCP,其主要原料为工业废料,价格低廉,SCP 早强抗冻减水剂掺入混凝土后,其减水率可达15%以上。抗冻效果也极为良好,表现在经-20℃冻后,再在标准条件下养护,比仅在标准条件下养护的混凝土强度仍然有明显增加.其早强效果表现在掺入了 SCP 的混凝土与未掺的混凝土相比,其强度三天龄期提高65—80%,七天龄期提高60～81%;14天 The building material room of Shanxi Institute of Building Research has recently developed a highly effective early-strength antifreeze and water reducing agent SCP. Its main raw material is industrial waste, and its price is low. After SCP early strength anti-freeze and water reducing agent is mixed with concrete, the water reduction rate can be improved. Up to 15%. The antifreeze effect is also very good. After being frozen at -20°C and then cured under standard conditions, the strength of concrete cured under standard conditions is still significantly increased. Its early strength performance is reflected in the concrete that incorporates SCP. Compared with unmixed concrete, its strength is increased by 65%-80% at the three-day age and 60-81% at the seven-day age; 14 days
