Abstract

The invention relates to an emulsion type two-component interface agent, which is formed by a component A and a component B. The component A is prepared from mixing the following components in percentage by weight: 46.0 to 55.9 percent of rapid hardening cement, 0 to 6.3 percent of ordinary cement, 37.2 to 47.0 percent of quartz sand, 5.8 to 6.2 percent of active mineral admixture, 0.2 to 0.4 percent of water reducing agent, 0.1 to 0.2 percent of boric acid, 0.01 percent of hydroxypropyl methyl cellulose, and 0.09 percent of analytically pure lithium carbonate; and the component B is prepared from mixing the following components in percentage by weight: 33.3 to 40.5 percent of latex, 1.1 to 1.2 percent of Basf water-based defoaming agent, and 58.4 to 65.5 percent of water. The emulsion type two-component interface agent provided by the invention has higher early strength, high bonding strength, good durability, and capability of enhancing concrete surface performances or endowing a concrete surface with required functions.

Description

technical field [0001] The invention relates to the technical field of engineering, in particular to an emulsion type two-component interface agent. Background technique [0002] Due to the development of the economy, large-scale construction of traffic infrastructure such as roads and bridges is bound to be carried out; after the completion of the roads and bridges, in the later period of continuous use, due to natural or man-made factors, various road structures will inevitably appear. problem, which requires repairs to the road surface. In the process of repairing, the bonding strength of old and new concrete is the key to the quality of the repaired and reconstructed concrete. [0003] At present, the interface agents used in my country's engineering mainly include cement paste, expanded cement paste, epoxy glue, fly ash modified cement mortar, etc., but the bonding strength of new and old concrete repaired or reinforced by using this type of interface agent is low, Poo...
