Abstract

The invention discloses sound insulation mortar, which is prepared from the following components in parts by weight: 30-50 parts of cement, 7.5-15 parts of fly ash, 8-12 parts of bagasse, 15-19 partsof vitrified micro beads, 14-34 parts of machine-made sand, 1-3.5 parts of hydroxypropyl methyl cellulose ether, 3-5.5 parts of redispersible latex powder, 0.1 part of lauryl sodium sulfate, 0.5 partof starch ether and 1 part of PP anti-cracking fiber. The sound insulation mortar has good construction performance, substantially improved sound insulation effect and substantially improved strength,enhances the bonding force with a floor, substantially reduces the hollowing condition, increases the tension extreme value of mortar, and basically eliminates the cracking condition.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a soundproof mortar. Background technique [0002] With the development of science and technology, the requirements for buildings are getting higher and higher, and noise control is one of them. National standards have requirements for the noise of building floors, such as GB / T50121-2005 "Building Sound Insulation Evaluation Standard", GB 50118 -2010 "Code for Sound Insulation Design of Civil Buildings", GB 50368-2005 "Code for Residential Buildings", GB / T 19889.7-2005 "Sound Insulation Measurement of Acoustic Buildings and Building Components Part 7: Field Measurement of Floor Slab Impact Sound Insulation" There are related requirements for this. At present, ordinary mortar can hardly meet the corresponding requirements for controlling floor noise. Sound insulation mortar also came into being. It is mainly composed of cementitious materials (cement), lightweight material...
