Abstract
The invention belongs to building mortar, and relates to chip building mortar. With the development of the building industry, river sand is consumed more, the yield of the river sand is less and less, and natural river sand resource is in shortage increasingly. Stone chips are utilized to replace the sand, and prepared into the chip building mortar by mortar thickening powder technology. The chip building mortar is prepared from the following substances by weight portion: 10 to 22 portions of cement, 12 to 78 portions of stone chips, 0.5 to 2.6 portions of mortar thickening powder, 0 to 15 portions of fly ash, 0 to 67 portions of sand and 10 to 20 portions of water by evenly stirring, and the grain diameter of the stone chips is less than 5mm. The chip building mortar has the advantages of saving the river sand resource, having small consumption of mortar and the cement and low cost of the mortar, improving the compressive strength and tensile bonding strength of the mortar, and reducing environmental pollution and land occupied by stone chip waste.
Description
Technical field
The invention belongs to mortar for building, specifically a kind of chip building mortar
Background technology
Mortar is important material of construction, and along with the development of modern architecture industry, the mortar usage quantity constantly increases.Natural river sand is the important component of mortar, also is Nonrenewable resources simultaneously.Along with the development of construction industry, river sand consumption increases, and river sand output is fewer and feweri.Many countries, for example European shortage that has occurred to river sand has influenced the development of construction industry; The natural river sand resource of China also faces the situation of worsening shortages.So invent a kind of high-performance, low cost, use the river sandy plain material in other material substitution mortar that extensively exists, be the vital task of building material industry.
Summary of the invention
The object of the present invention is to provide a kind of high-performance, low cost, use chipped material to substitute the river sandy plain material in the mortar, need not or seldom use the chip building mortar of river sand.
Another object of the present invention is to provide the preparation method of above-mentioned building mortar.
The object of the present invention is achieved like this:
Chip building mortar, form by following materials in part by weight:
Cement 10-22 part mortar densification powder 0.5-2.6 part
Flyash 0-15 part sand 0-67 part
Stone fragment 12-78 part water 10-20 part.
The stone fragment particle diameter is less than 5mm.
Described flyash is a kind of or wherein two or more mixture in the low calcium fly ash of I level, the low calcium fly ash of II level, I level high-calcium fly ass, the II level high-calcium fly ass.
Main points of the present invention are: utilize stone fragment to substitute river sand, produce building mortar, utilize the operability of densification powder technical guarantee mortar.
In order to satisfy the needs of civil construction project, every year all will be excavated a large amount of mountain stone resources by the world, in the stone product of the required mountain of production construction work, also produces a large amount of chips " waste material ".As by product, these stone fragments mostly are not utilized effectively, then both occupied ground, contaminate environment again.The present invention utilizes stone fragment to substitute river sand and produces building mortar, has both utilized the by product of mountain stone product, has protected environment, has saved river sand resource again.
The stone fragment source that the present invention uses has two: one, the byproduct of rubble processing, and the 2nd, reprocessing forms to rubble; The stone fragment particle diameter is all below 5mm.Under the condition that river sand resource is arranged, also can use or add part river sand.
The flyash that the present invention uses is one or more mixture of the low calcium fly ash of I level, the low calcium fly ash of II level, I level high-calcium fly ass, II level high-calcium fly ass etc.
For the workability and the operability that guarantee the chip mortar, the present invention uses the water-keeping thickening material mortar densification powder.Mortar densification powder can significantly improve the workability of premixing mortar, the building mortar of densification powder and flyash preparation has characteristics such as operability is good, cohesive strength is high, water-fast, and frost resistance is good, be a kind of material of construction of superior performance, extensively be subject to people's attention.
The present invention utilizes stone fragment to substitute sand, and utilizes the mortar densification powder technology to be mixed with chip building mortar.The chip strength classes of mortar can reach M30.This chip building mortar material has good water-retentivity and operability, reduced the sand consumption, reduced cement consumption, mortar ultimate compression strength and tensile bond strength have been improved, reduced the soil that the stone fragment solid waste takies, reduce environmental pollution, saved the energy, for construction industry provides a kind of high-performance, building mortar material cheaply.
Advantage of the present invention is:
1. save river sand resource.
2. cement consumption is few.
3. mortar ultimate compression strength and tensile bond strength have been improved.
4. the chip building mortar cost is low.
5. minimizing environmental pollution.
6. reduced the soil that the chip waste takies.
