河南省建一公司试验室研究成功水泥抗压强度促凝加压蒸养快速测定法。该法利用国际GB177-77水泥胶砂强度检验设备,辅以(?)28厘米手提式高压蒸煮器,在水泥胶砂中掺入适量的SC型复合促凝剂,使用1公斤/厘米~2的蒸汽压力,使常规标养28天的试验周期缩短到3.5小时,提高测试工效190余倍。该公司曾用此法先后对本省和国家建材研究院水泥所提供的水泥,进行了大量试验。在回归分析 Henan Province Jianyi company laboratory successfully developed a cement compressive strength accelerating coagulation pressure steaming and rapid determination method. The method uses international GB177-77 cement mortar strength testing equipment, supplemented with (?) 28 cm portable high-pressure cooker, in the cement mortar mixed with the right amount of SC type compound coagulant, using 1 kg/cm~2 The steam pressure has shortened the standard 28-day test period to 3.5 hours and improved the testing efficiency by more than 190 times. The company used this method to conduct a large number of tests on the cement provided by the provincial and national building materials research institutes. In regression analysis
