Low-strength composite mortar doped with glass bead aggregate and plant fibers and preparation method thereof

Abstract

The invention provides low-strength composite mortar doped with glass bead aggregate and plant fibers and a preparation method thereof and belongs to the field of building materials. The low-strength composite mortar is formed by mixing cement, a mixed aggregate, the plant fibers, a lime paste and water at a weight ratio of 1:(8-12):(0.12-0.80):(0.8-1.3):(1.2-1.5); the mixed aggregate is a mixture of glass beads and natural fine sand; the mass percent of the glass beads is 70%-85%; the glass beads adopt reproducible glass beads which take crushed glass and the like as raw materials and are the glass beads with the diameter of 3.5-5mm; the fine sand is natural sand and the maximum grain diameter passes through a sieve hole with the size of 1.5mm; the plant fibers comprise natural plant fibers with good flexibility and good blocking property, such as hemp fibers, bamboo fibers and cotton stalk fibers; the lime paste is a product obtained by curing lime stones. The low-strength composite mortar has the advantages of low cost, environment-friendly and easily-available materials, wide distribution and less energy consumption. The method is simple to operate and is easy to construct.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a shock-isolation layer mortar used for masonry between a village building superstructure and a foundation and a preparation method thereof. Background technique [0002] As a civil engineering material, mortar is widely used in masonry, plastering or decoration works in civil construction. Its main raw materials are cement, sand, water and other additives. [0003] The principle of foundation isolation is to add a support element with a small horizontal stiffness between the foundation and the superstructure, so that the natural vibration period of the superstructure is prolonged, and it is far away from the excellent period of the earthquake action, thereby reducing the impact of the earthquake action on the superstructure and alleviating Earthquakes protect people's lives and property. Although the basic isolation technology has been applied in high-rise buildin...
