Abstract

The invention relates to anti-skid cement mortar and a preparation method thereof. The anti-skid cement mortar comprises the following components in percentage by weight: 10-40 percent of high-molecular polymer, 10-40 percent of cement, 20-50 percent of water and 30-60 percent of engineering fine sand. The sum of the percentages of the components is 100%. The preparation method of the anti-skid cement mortar comprises the following steps: (1) pouring water, cement, high-molecular polymer and engineering fine sand into a clean agitation vat in proportion in sequence; (2) uniformly agitating the cement mortar raw materials for 30min in a normal-temperature environment with an agitator fixed above the agitation vat; and (3) pouring fully and uniformly agitated cement mortar into a charging bucket for use. The anti-skid cement mortar and the preparation method thereof overcome the defects of poor friction performance, high possibilities of skidding, cracking and corrosion and poor ductility of conventional cement mortar material, and solve the problems of high energy consumption, severe environmental pollution and long construction period during preparation of the conventional cement mortar material.

Description

technical field [0001] The invention belongs to the field of cement mortar, and in particular relates to an anti-skid cement mortar and a preparation method thereof. The invention provides an anti-skid cement mortar maintenance material for concrete cement pavement, and a preparation method of the anti-skid cement mortar. Background technique [0002] During the service period, the concrete pavement not only bears tens of thousands of wheel loads, but also withstands the influence of periodic changes in temperature and humidity in the environment, which eventually leads to various damages. Concrete pavement diseases are mainly manifested as cracks, subsidence, severely broken slabs, cracked slab corners, mud pumping, misalignment, damage to joint materials, etc. If these diseases are not maintained and repaired in time, the performance of the pavement will decline rapidly. [0003] The deep-rooted reason for the above-mentioned lesions on the concrete pavement is that althou...
