Mortar test block suitable for impermeability detection of polymer cement waterproof coating and preparation method thereof
The invention discloses a preparation method of a mortar test block suitable for impermeability detection of a polymer cement waterproof coating, which comprises the following steps: detecting the 3d compressive strength of cement, and designing the formula of the mortar test block according to the value of the 3d compressive strength of the cement; the preparation method comprises the following steps: weighing raw materials according to a designed formula, and uniformly mixing to obtain standard slurry; stirring the standard slurry to obtain mortar; pouring the mortar into the anti-permeability test mold for multiple times, compacting each time until the anti-permeability test mold is completely filled, and finally striking off the mortar in the anti-permeability test mold to obtain a sample; and curing the molded sample, then removing the mold to obtain a rough test block, immersing the rough test block into water, curing again, taking out the rough test block after curing is finished, grinding mortar on the two surfaces of the rough test block, and then airing to obtain the mortar test block. The permeable pressure of the prepared mortar test block is 0.3 MPa-0. 4MPa, the overall uniformity of the test block is good, and the problems that the permeable pressure fluctuation of the impermeable standard mortar test block is large, and the uniformity is poor are solved.
本发明公开了一种适用于聚合物水泥防水涂料抗渗性检测的砂浆试块的制备方法，包括如下步骤：检测水泥的3d抗压强度，根据水泥3d抗压强度的值设计砂浆试块的配方；按照设计的配方称取原料，混合均匀，得到标准浆体；将标准浆体进行搅拌，得到胶砂；将胶砂分多次倒入抗渗试模中，每次均振实，直至完全填充抗渗试模，最后将抗渗试模中胶砂刮平，得到试样；将成型好的试样养护后拆模，得到粗试块，将所述粗试块浸入水中并再次养护，养护结束后取出，将粗试块两面的灰浆打磨后晾干，得到所述砂浆试块。本发明制备得到的砂浆试块的透水压力为0.3MPa～0.4MPa，试块整体匀性好，解决了抗渗基准砂浆试块透水压力波动较大，均匀性较差的问题。
