Abstract

The invention discloses a masonry mortar produced by construction solid waste. The masonry mortar comprises the following raw materials in parts by weight: 150-200 parts of cement, 900-1,200 parts of construction solid waste, 20-30 parts of glazed hollow beads, 30-40 parts of limestone, 10-20 parts of shell powder, 2-3 parts of magnesium sulfate heptahydrate, 5-10 parts of redispersible emulsion powder, 2-3 parts of polytetrafluoroethylene fibers, 0.8-1 part of Butyl tin tris-2-ethylexanoate, 2-3 parts of calcium phosphate, 4-6 parts of graphite powder, 1-2 parts of nano carbon powder, 1-2 parts of aluminium dihydric phosphate, 0.8-1 part of triethavolamine oleate soap and 2-4 parts of aluminum nitride powder. The masonry mortar provided by the invention is low in cost, can be used only by adding water and uniformly stirring according to the required amount during construction operation, is low in material consumption and waste, and has the advantages of high adhesion strength, low dry shrinkage rate, excellent anti-freezing durability, low thermal conductivity, good heat preservation performance, favorable workability, environmental friendliness and innocuity.

Description

A kind of masonry mortar that utilizes building solid castoff to produce
Technical field
The present invention relates generally to a kind of masonry mortar, relates in particular to a kind of masonry mortar that utilizes building solid castoff to produce.
Background technology
The use of the building solid castoffs such as waste concrete block, standard fragment of brick and (hollow) air-entrained concrete building block has become energy-conservation requirement and the material that generally uses, but because monomer whose is larger, intensity is relatively low, therefore be easy to produce the building block of losing fangle due to misoperation in handling process, this part building block can not be on main construction.Producer's aerating or work as building waste and throw away is again transported in processing in the past often back.These two kinds of methods all can produce the larger wasting of resources, and project seminar divides and severally distinguishes application below according to engineering practical situation for this reason, and buy disintegrating apparatus and building castoff is carried out to fragmentation reclaim:
Discarded concrete is directly carried out after fragmentation, obtain the sand shape soil of different thicknesses, mix and stir according to certain proportioning with cement, additive etc., be recycling in masonry mortar, wall plastering mortar.
Summary of the invention
The object of the invention is exactly for a kind of masonry mortar that utilizes building solid castoff to produce is provided.
The present invention is achieved by the following technical solutions:
A masonry mortar that utilizes building solid castoff to produce, it is comprised of the raw material of following weight parts:
Cement 150-200, building solid castoff 900-1200, glass bead 20-30, Wingdale 30-40, oyster shell whiting 10-20, magnesium sulfate heptahydrate 2-3, redispersable latex powder 5-10, polytetrafluoroethylene fiber 2-3, three sad butyl tin 0.8-1, calcium phosphate 2-3, Graphite Powder 99 4-6, nano-carbon powder 1-2, aluminium dihydrogen phosphate 1-2, trihydroxy ethylamine oleate soap 0.8-1, aluminum nitride powder 2-4;
Described building solid castoff is waste concrete block, standard fragment of brick and (hollow) air-entrained concrete building block etc.
Advantage of the present invention is
Masonry mortar of the present invention is with low cost, when construction operation, only need measure on request and add water and stir and can use, spillage of material, less wastage, have that cohesive strength is high, contract with dry rate is low and Frost Resistance is good, thermal conductivity is low, good heat preservation performance, workability are good, environment-protecting asepsis.
Accompanying drawing explanation
Fig. 1 has of the present inventionly carried out screen experiments table to the regeneration aggregate after concrete, aerated blocks, standard square fragmentation;
Embodiment
Embodiment 1
The masonry mortar that utilizes building solid castoff to produce, it by following weight parts (kilogram) raw material form:
Cement 170, building solid castoff 1000, glass bead 30, Wingdale 40, oyster shell whiting 16, magnesium sulfate heptahydrate 3, redispersable latex powder 10, the sad butyl tin 0.8 of polytetrafluoroethylene fiber 3, three, calcium phosphate 2, Graphite Powder 99 4, nano-carbon powder 1, aluminium dihydrogen phosphate 2, trihydroxy ethylamine oleate soap 0.8, aluminum nitride powder 2;
Described building solid castoff is waste concrete block, standard fragment of brick and (hollow) air-entrained concrete building block etc.
Screen experiments: the regeneration aggregate after concrete, aerated blocks, standard square fragmentation has been carried out after screen experiments, and wherein the regeneration aggregate fineness modulus of aerated blocks fragmentation is 2.6, according to GB/T25176-2010 the 4.2nd standard, is assessed as medium sand.Regeneration aggregate fineness modulus after concrete disintegrating is 3.1, according to GB/T25176-2010 the 4.2nd standard, is assessed as coarse sand.Regeneration aggregate fineness modulus after standard square fragmentation is 3.4, according to GB/T25176-2010 the 4.2nd standard, is assessed as coarse sand.And the fineness modulus of project management department's starting material mountain sand is 2.7, be assessed as medium sand.So reworked material screen experiments all can reach the requirement of sand.
Performance test:
