一、概述“用促凝压蒸技术一小时推定混凝士强度试验”用于混凝土生产及施工的质量管理,对于保证工程质量、防止质量事故,节约水泥具有良好的技术经济效果和社会效益。由于该项试验采用手工筛分混凝土砂浆及成型试件,所以当混凝土拌合物比较干硬、灰水比较大时,存在费时费力、试验误差可能增大,影响推定精度等问题。 First, an overview of “Coagulation pressure steaming technology one hour presumptive coagulation test” for concrete production and construction quality management, to ensure project quality and prevent quality accidents, saving cement has a good technical and economic results and social benefits. Because of this test manual screening of concrete mortar and forming specimens, so when the concrete mixture is relatively dry and hard, gray water is relatively large, there are time-consuming and labor-intensive, the test error may increase, affecting the accuracy of the presumption and other issues.
