Abstract

The invention relates to multi-component extrusion-type mortar as well as a preparation method and use method thereof. The extrusion-type mortar is composed of an A component, a B component and a C component; the A component includes cement, baked sand, epoxy resin and a water-based toughening dilution modifier, or the A component includes cement, baked sand, epoxy resin, a water-based tougheningdilution modifier and a thixotropic agent; the B component includes a water-based epoxy curing agent, metakaolin, fly ash, mineral slag, a water-based toughening dilution modifier, an accelerator anda thixotropic agent; the C component is water; and the mass ratio of the A component to the B component to the C component is 3.0:1.0:0.3 to 3.8:1.0:0.3. The multi-component extrusion-type mortar provided by the invention can be used for masonry and bonding, can be stored stably for a long time, the preparation method is simple, the workability is good, and the mortar has higher early strength andlater strength.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a multi-component extrusion mortar. Background technique [0002] Cement mortar is generally made of cement, sand and water in a certain proportion, and is widely used in construction projects. Cement mortar can be divided into site-mixed mortar and ready-mixed mortar according to the application form, and ready-mixed mortar can be divided into dry-mixed mortar and wet-mixed mortar. Ordinary dry-mixed mortar is generally pre-mixed in the factory, then mixed with water on site, and then pumped for construction. Compared with traditional mortar, dry-mixed mortar has greatly improved stability, but there are still problems such as inaccurate measurement, poor homogeneity and dust hazards. In addition, the general setting time of ordinary dry-mixed mortar is specified as 3h to 8h. Wet-mixed mortar will generally be transported to the place of use by a mixer truck after the cement,...
