Description
技术领域technical field
本发明属于材料技术检测技术领域，尤其涉及一种胶凝材料浆体表观密度快速测试装置。The invention belongs to the technical field of material technology detection, and in particular relates to a rapid testing device for apparent density of cementitious material slurry.
背景技术Background technique
目前，业内常用的现有技术是这样的：At present, the existing technologies commonly used in the industry are as follows:
胶凝材料作为多孔混凝土的核心组成部分，其浆体的表观密度是多孔混凝土配合比设计的关键指标。胶凝材料用量、浆体对多孔混凝土孔隙的填塞程度与多孔混凝土的孔隙率有着密切的关系，而浆体的表观密度直接影响着胶凝材料用量的大小、水胶比的确定以及拌合物的工作状态。对工作性能良好的胶凝材料浆体表观密度进行准确测试，保证胶凝材料用量以及浆体对砂石骨料的有效包裹和粘结，才能得到孔隙率和力学性能最佳的多孔混凝土结构。The cementitious material is the core component of porous concrete, and the apparent density of its slurry is a key index for the design of the mix ratio of porous concrete. The amount of cementitious material, the filling degree of the slurry to the pores of the porous concrete are closely related to the porosity of the porous concrete, and the apparent density of the slurry directly affects the amount of the cementitious material, the determination of the water-binder ratio and the mixing process. working state of the thing. Accurately test the apparent density of the cementitious material slurry with good working performance to ensure the amount of cementitious material and the effective wrapping and bonding of the slurry to the sand and gravel aggregate, in order to obtain a porous concrete structure with the best porosity and mechanical properties .
目前，现有技术中关于胶凝材料浆体表观密度的确定，一种方法是采用理论计算的方法，即通过测定组成胶凝材料浆体的各物料真密度，结合各物料的占比情况等已知条件直接计算混合物浆体密度。由于需要事先获取各类物料的真密度，除了实际操作耗时繁琐外，一方面增加了配合比设计的难度，一方面也降低了配合比设计的及时性和应变性。另一种方法是参考砂浆表观密度测试的方法，即测试固定体积容器中的浆体质量，再根据公式计算获得浆体表观密度。但一方面受浆体稠度影响，装料过程中裹挟的气体难于通过敲击排出，另一方面由于容器开口面积大，浆体试样需求量大，具体测试操作上存在一定难度，且这一方法测试的数值精确度欠佳。At present, in the prior art, one method for determining the apparent density of cementitious material slurry is to adopt a theoretical calculation method, that is, by measuring the true density of each material that makes up the cementitious material slurry, combined with the proportion of each material Calculate the slurry density of the mixture directly under known conditions. Due to the need to obtain the true density of various materials in advance, in addition to the time-consuming and cumbersome actual operation, on the one hand, it increases the difficulty of mix ratio design, and on the other hand, it also reduces the timeliness and adaptability of mix ratio design. Another method is to refer to the method of mortar apparent density test, that is, to test the mass of slurry in a fixed volume container, and then calculate the apparent density of slurry according to the formula. However, on the one hand, due to the influence of the slurry consistency, it is difficult to discharge the gas trapped in the filling process by knocking; on the other hand, due to the large opening area of the container, the demand for slurry samples is large, and there are certain difficulties in the specific test operation. The numerical precision of the method test is poor.
因此，研制一种能简单、有效、快速地测试胶凝材料浆体表观密度的装置，减少繁琐的测试过程，意义深远。Therefore, it is of far-reaching significance to develop a device that can simply, effectively and quickly test the apparent density of cementitious material slurry and reduce the tedious testing process.
综上所述，现有技术存在的问题是：In summary, the problems in the prior art are:
装料过程中裹挟的气体难于通过敲击排出，具体测试操作上存在一定难度，测试的数值精确度欠佳。The gas entrapped in the charging process is difficult to be discharged by knocking, and there are certain difficulties in the specific test operation, and the accuracy of the test value is not good.
解决上述技术问题的难度和意义：The difficulty and significance of solving the above technical problems:
难度在于受浆体稠度影响，另一方面由于容器开口面积大，浆体试样需求量大；意义在于可快速有效的对胶凝材料的表观密度进行检测，减少繁琐的测试过程。The difficulty lies in the influence of the consistency of the slurry. On the other hand, due to the large opening area of the container, the demand for slurry samples is large; the significance lies in the fact that the apparent density of the gelled material can be detected quickly and effectively, reducing the tedious testing process.
