Floor-heating heat-preservation mortar with good gas permeability

Abstract

The invention relates to floor-heating heat-preservation mortar with good gas permeability. The mortar is prepared from, by weight, 10-20% of pulverized fuel ash, 10-20% of cement, 10-12% of fine sand, 30-50% of sludge balls, 15-20% of limestone, 8-10% of limestone tailings and 5-7% of yellow sand. The product prepared by means of the method has better triability, low cost and good gas permeability.

Description

technical field [0001] The invention discloses a floor heating and heat preservation mortar with good air permeability. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials and water. It is also called mortar and mortar. Commonly used mortars include cement mortar, mixed mortar, lime mortar and clay mortar. The mixing of mortar The general mortar mixer is required to mix evenly. Most of the existing floor heating mortars have weak trial performance, high cost and insufficient air permeability. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a floor heating and thermal insulation mortar with good air permeability, better trial performance, lower cost and better air permeability. [0004] In order to achieve the above object, the present invention is achieved through the following technical solution...
