Concrete surface reinforcing agent is a water-soluble liquid chemical hardener with colorless and transparent appearance. One component materials are common in the market. The main components of concrete surface reinforcement agent are reactive alkali metal silicate or modified alkali metal silicate, catalyst auxiliary Etc. The concrete surface reinforcing agent has * * * low surface tension, which can quickly penetrate into the concrete, and react with the by-product of cement hydration in the concrete, such as calcium hydroxide, to generate a large number of silica gel, which can block the capillary pores in the concrete, thus increasing the compactness, compressive strength, hardness and wear resistance of the concrete surface, Which can generally improve the strength of concrete 15-30% 。 The concrete surface reinforcing agent must be applied to the formed cement mortar Or concrete surface: one In order to ensure that the concrete surface reinforcing agent can penetrate into the concrete more, it is recommended that the newly constructed cement mortar or concrete surface (preferably polished by machine) be seven The construction shall be carried out after wet curing and complete drying. Of course, some concrete surface reinforcements are completed on the new construction ground in order to save materials and construction period twenty-four Apply after hours. two . Due to various reasons, the strength of the cement mortar or concrete floor surface is not enough, and the ash and sand rise, the concrete surface reinforcement can be used for hardening and dust prevention treatment: the surface hardness and wear resistance of the treated floor are significantly increased, and no ash and sand rise, but this treatment method does not change the appearance of the original floor. Therefore, It will not repair the damage of the original ground. If you want to repair the damage of the original ground (such as holes, cracks, etc.), you must take the method of repair or overall polishing. three Surface sealing and strengthening of terrazzo floor or emery wear-resistant floor Marble The effect of the ground. four Surface reinforcement of concrete products or concrete components containing cement: for the surface reinforcement of concrete components, it should be noted that the better the original strength of concrete components is, the smaller the range of concrete surface reinforcement can be improved C30 For the above concrete, the concrete surface strengthening agent has little ability to improve its strength.
