Abstract

The invention discloses composite cement mortar. The composite cement mortar is prepared from, by weight, 30-40 parts of cement, 5-10 parts of bamboo fiber, 20-40 parts of river sand, 1-5 parts of mineral powder, 3-10 parts of kaolin, 5-10 parts of montmorillonite, 5-10 parts of sodium acetate, 2-5 parts of water reducer, 2-5 parts of mica, 2-5 parts of natrium aceticum, 5-10 parts of thickening agent, 2-5 parts of glycerin, and the balance of water. The composite cement mortar has the advantages that the crack resistance performance of the cement mortar is improved, and the strength of the product is improved, so that the cement mortar has the remarkable advantages of strong adhesion force, crack resistance, durability and high strength.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a composite cement mortar. Background technique [0002] Cement is widely used as a hydraulic cementing material in the field of construction engineering. Its main characteristic is its plasticity after adding an appropriate amount of water. It can harden not only in the air but also in water. Cement is particularly suitable for making concrete, and is widely used in pavement paving, housing construction and other occasions. The existing cement on the market is prone to premature fracture and destruction under cold weather conditions, which brings inconvenience and waste to production and life. Summary of the invention [0003] The purpose of the present invention is to provide a composite cement mortar, the weight ratio of each component of the cement mortar is: 30-40 parts of cement, 5-10 parts of bamboo fiber, 20-40 parts of river sand, 1-5 parts of mineral powder , Kaolin 3-10 p...
