Abstract
The present invention relates to one kind of building mortar material comprising cement 8-20 wt%, thickening powder 2-4 wt%, flyash 5-10 wt%, sand 50-70 wt% and building residue 8-23 wt%. The building mortar has solid waste from power plant and waste concrete material of building site as partial material, and can reduce waste occupied land and environmental pollution and lower its cost.
Description
Technical field
The present invention relates to a kind of building mortar material, particularly be mixed with the building mortar material of building slag, flyash and cement.
Background technology
The quantity of China's building waste has accounted for 30%～40% of municipal wastes total amount.According to statistics, China's building waste that only construction produced and discharged every year just has 40,000,000 tons.Overwhelming majority building waste adopts the mode of air storage or landfill to handle, and causes environmental pollution.In the building waste brick and tile and broken concrete etc.
On the other hand, China every year is all being built a large amount of new buildingss, and build by laying bricks or stones, plastering engineering is the important component part in the construction work, therefore needs a large amount of building mortar materials.If can be converted into building waste a part of raw material of building mortar material, then help reducing and stack or soil that landfill solid building castoff takies, reduce environmental pollution, can be construction industry simultaneously a kind of lower-cost New Building Materials are provided.
Summary of the invention
The objective of the invention is to utilize the building slag for raw material prepares a kind of high strength, the building mortar material of low material cost.
To achieve these goals, the invention provides a kind of building mortar material, it consists of: 8～20 weight % cement, 2～4 weight % densification powders, 5～10 weight % flyash, 50～70 weight % sand and 8～23 weight % building slag.
Building mortar material of the present invention has that operability is good, cohesive strength is high, water-fast, characteristics such as frost resistance is good, is a kind of New Building Materials of superior performance, is subject to people's attention gradually.
Embodiment
Building mortar material of the present invention is made up of cement, densification powder, flyash, sand and building slag.
Used cement meets the requirement of GB175-1999 " silicate cement, ordinary Portland cement " among the present invention.Example commonly used is 42.5 grades of ordinary Portland cements, 32.5 grades of ordinary Portland cements, 32.5 grades of Portland blasts, and the most frequently used is 32.5 grades of ordinary Portland cements or 32.5 grades of Portland blasts.
Used densification powder is a water-keeping thickening material among the present invention.One preferred embodiment in, the present invention uses " building section " board densification powder of producing available from ShangHai JianYan Building Materials Science Co., Ltd.
Used flyash meets the requirement of GB1596-1991 " flyash that is used for cement and concrete " among the present invention.The example of the used flyash of the present invention comprises that the II level hangs down calcium fly ash, II level high-calcium fly ass or their mixture.
Used sand meets the requirement of GB/T14684-2001 " building sand " among the present invention, and fineness modulus is 2.3～3.0 medium sand.
The used building slag of the present invention is broken concrete material, broken brick, useless building mortar material, the solid waste of power plant emission or their mixture, and the maximum particle diameter of described building slag is less than 5mm.The production technique of above-mentioned building slag is with the solid waste of waste concrete material, useless brick, useless building mortar material, power plant emission or their mixture letter sorting (rejecting reinforcing bar) → pulverize → sieve → the have building slag of the present invention of required particle diameter.
Following with reference to embodiment, the present invention is further illustrated.But will be understood that embodiment only is an illustrative, and should not provide constraints to protection scope of the present invention.
