Basic Characteristics of Broken Stone Concrete

碎石砼的基本特性研究

Detection of gravel for the design, construction effects, in the course of the study, the technique of crushed stone for the two key indicators-broken concrete and broken after the size of carrying capacity, to carry out rubble of experimental design.

为检测碎石化设计、施工效果，在研究过程中，针对碎石化技术的两大关键指标&水泥混凝土破碎尺寸和破碎后承载能力，进行碎石化试验设计。

Non-explosive demolition technology was also called as static rock-broken technology or static blast technology, which supplies the controlled blasting technology greatly. It was widely used in stone exploiting, concrete fracturing, rock digging and high slope trimming and so on.

静态破裂技术亦称静态破石技术、无声破碎技术、静态爆破技术等。其作为控制爆破的一个重要补充，在石材开采、混凝土破碎、岩石开挖和高边坡修整等工程领域得到广泛应用。

On the basis of studying influences of broken stone granular behavior on concrete property and granular evaluation index, this paper puts forward a proposal that broken stone granular should be graded according to its quality.

在研究碎石粒形特性对砼性能的影响及粒形评价指标的基础上，提出了对碎石粒形进行质量分级的建议。
