Mixed Concrete

Concrete is the most extensively used material in building and civil project structure. With the rapid development of economic construction, urban construction and infrastructure construction increase year by year, so there is a greater demand for concrete, which brings the rapid development of ready-mixed concrete industry. During the rapid development, structural safety and durability problems caused by concrete quality appear frequently. Meanwhile, to implement the fundamental national policies of resource conservation and environment protection, according to Green Building Action Plan (GUOBANFA [2013] No.1) approved by CPC Central Committee and the State Council, besides meeting the quality requirements, ready-mixed concrete must also meet the green products requirements of "energy conservation, emission reduction, safety, convenience and recyclability" for the vigorous development of green building material and supporting the requirements for building energy conservation, green building and new-type urbanization construction. By quality testing, this paper elaborates the green assessment technology for ready-mixed concrete in combination with raw material quality control, design of mix ratio, production process quality control, construction process quality control, residual concrete treatment, hardened concrete quality control, and control of dust, noise and wastewater. The greening of ready-mixed concrete brings the production and application of green building material, promotes the transformation and upgrading of building material industry and drives the development of green building.

In this article, the Tabular CUSUM (Cumulative Sum) Charts statistic method is employed to analyze the strength quality control of ready-mixed concrete for rigid pavement, for which the CUSUM is also used to analyze and monitor the micro changes of process mean for the strength of the ready-mixed concrete. The result of analytical study supports that the CUSUM statistical analysis skill is more sensitive than the Shewhart Control Chart in terms of designed mixing ratio parameter, water-cement ratio, and admixtures analyzed under the same concrete strength. When micro changes are presented in continuous mean strength value of the ready-mixed concrete, it can detect the continual changes of the concrete quality in a more accurate way. By combining the CUSUM statistical analysis and Shewhart Control Chart, higher accuracy of the quality control analysis could even be achieved in order the enhance quality control performance when pouring the ready-mix concrete on rigid pavement.

Cracks in the floor slab is a common problem and should be paid great attention in construction. In this paper, combining with an example, the cause of cracks in cast-in-place concrete slabs has been analyzed, then proposed control measures of cast-in-place floor crack.The control measures has a certain reference value for management and quality control of concrete construction work.
