在建筑企业中,混凝土质量控制成了一个企业技术水平的重要标志,特别是大规模经济建设的到来,乡镇建筑队伍的兴起,队伍素质远远不能适应建设的需要,有的凭老经验办事,不区别原材料条件,一味追求“安全”,任意加大用灰量,其结果造成质量事故或隐患.而混凝土材料的不均匀性影响着新浇混凝土和硬化混凝土的性能,若混凝土各种配料具有合适的比值,就会使新浇混凝土的和易性及密实度达到预期的要求,并使硬化混凝土具有一定的强度和耐久性.
In construction companies, concrete quality control has become an important symbol of an enterprise’s technological level. In particular, the arrival of large-scale economic construction, the rise of the township construction team, the quality of the team can not meet the needs of the construction, and some work with the old experience. Without distinguishing raw material conditions, blindly pursuing “safety” and arbitrarily increasing the amount of ash used, resulting in quality accidents or hidden troubles. The non-uniformity of concrete materials affects the performance of freshly poured concrete and hardened concrete, if the various ingredients of concrete have The proper ratio will make the new concrete concrete workability and density meet the expected requirements, and make the hardened concrete has a certain degree of strength and durability.
