Abstract
The invention discloses low-cost high-performance masonry mortar and relates to the technical field of building materials. The low-cost high-performance masonry mortar is prepared from 55-75% of solid waste fine aggregate, 15-30% of Portland cement, 5-8% of calcium sulfate, 3-5% of calcium oxide, 5-15% of bauxite, 5-8% of dickite powder, 5-10% of coal ash, 5-10% of nano-scale superfine silica powder, 0.5-0.7% of inorganic bentonite, 0.4-0.6% of wood fibers, 0.1-0.2% of water reducer, 0.05-0.07% of cellulose ether and 0.01-0.02% of starch ether. The high-performance mortar is prepared from building solid waste, materials can be saved, environmental friendliness is high, the mortar of the structure has the advantages of being free of shrinkage and achieving microdilatancy, water retention, crack resistance and bonding power, and strength is greatly improved.
Description
Technical field
The present invention relates to building material technical field, more particularly to a kind of masonry mortar of low-cost and high-performance.
Background technology
With the continuous development of building trade, the building waste in city is continuously increased, and newly-built building and tears open
The building that removes can produce substantial amounts of rubbish, be used as substantially again for more than 2.5mm building solid waste for diameter particle at present
Growing concrete, but the little particle building solid waste material of most below 2.5mm is difficult to process, and which main reason is that water absorption
Greatly, powder amount is big, low intensity is difficult by.
Content of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of low-cost and high-performance masonry mortar, by with thin
Based on the solid waste of grain below thing 2.5mm, a kind of mortar with high performance structures is defined.
Technical scheme is as follows：
A kind of low-cost and high-performance masonry mortar, composed of the following components：Solid waste fine aggregate 55～75%, silicic acid
Salt cement 15～30%, calcium sulfate 5～8%, calcium oxide 3～5%, aluminum vanadine 5～15%, dickite powder 5～8%, flyash 5
～10%, nano level superfine silica flour 5～10%, inorganic bentonite 0.5～0.7%, wood fibre 0.4～0.6%, water reducer
0.1～0.2%, cellulose ether 0.05～0.07%, starch ether 0.01～0.02%.
Further, nanometer powder organosilicon 0.5～0.6%, pure acrylic acid rubber powder 0.1～0.15% are also included.
Preferably, composed of the following components：Solid waste fine aggregate 60～68%, portland cement 17～24%,
Calcium sulfate 5～8%, calcium oxide 3～5%, aluminum vanadine 8～12%, dickite powder 5～8%, flyash 9～10%, nanoscale surpasses
Fine silica powder 5～7%, inorganic bentonite 0.5%, wood fibre 0.5%, water reducer 0.1%, cellulose ether 0.05%, starch ether
0.01%, nanometer powder organosilicon 0.5%, pure acrylic acid rubber powder 0.1%.
It is little that portland cement in the present invention has a drying shrinkage, anti-wear performance height, and condenses fast, the high advantage of intensity；
The calcium sulfate can be used for adjusting stirring setting time of the portland cement and the solid waste fine aggregate；Described
Calcium oxide can lift fire resistance rating while condensation effect is lifted；The bauxite can be carried jointly with the calcium oxide
Rise fire resistance rating；The dickite powder can lift expansion character；The flyash, can by the cooperation with the bauxite
The compound with hydraulic gelling property is generated, increases intensity and the durability degree of mortar；The nano level superfine silica flour can be carried
Rise intensity；The inorganic bentonite increases can mineral lattice spacing, make hydrone enter the crystal layer of mineral；The wooden fibre
Dimension can make moisture promptly be transferred to pulp surface and interface so that the uniform moisture distribution inside slurry significantly reduces skinning
Phenomenon, and adhesion strength and surface strength are significantly improved；The water reducer has peptizaiton, energy to portland cement granule
Improve its workability, reduce unit consumption of water, improve the mobility of compound；The cellulose ether can make the moisture in mortar
It is difficult to lose, and progressively discharges within long period of time, the water-retaining property for making mortar good and workability；The starch ether energy
Anti- hang down property and the anti-slipping property of mortar is enough significantly improved so as to higher yield value；And substantially increase mortar denseness,
Improve mobile performance, make construction more smooth, scrape smear smoother；It is higher that the pure acrylic acid rubber powder can make mortar integrally have
Intensity and impact resistance are strong have the advantages that shock resistance and shearing force.
Beneficial effect：The present invention prepares High Performance Mortar by using construction and demolition wastes material, can realize useless to solid
The recycling of material；The mortar of the structure in addition to the performance for possessing ordinary mortar, also have ungauged regions, microdilatancy, water-retaining property,
Crack resistance and cohesive force, while the mortar has corresponding hydrophobicity performance, anti-sag, self-leveling, can to meet 30MPaC following
Plant intensity.
