水泥新标准于今年1月1日起全面执行,水泥标号的检定,由硬练法改为软练法,改用双转叶片式胶砂搅拌机搅拌,胶砂震动台震动成型,使用4×4×16三联试模,先进行抗折试验,再以破坏后的试体,采用抗压夹具,使受压面积为4×6.25,进行抗压试验。关于抗折强度与抗压强度的计算,简介如下:1.抗折强度 Cement new standards on January 1 this year, the full implementation of the cement label verification, from hard method to soft training method, switch to dual rotary vane mixer agitator, plastic sand shaking table vibration molding, the use of 4 × 4 × 16 triple test mode, the first bending test, and then after the destruction of the test object, the use of anti-pressure fixture, the pressure area of ​​4 × 6.25, the compression test. About the calculation of the flexural strength and compressive strength, the brief introduction is as follows: 1. The flexural strength
