Abstract

The invention discloses the light masonry mortars prepared using discarded clay brick, including major ingredient, auxiliary material, it is characterized in that major ingredient grain size is 0.5~4.75mm, auxiliary material includes cement, flyash, silicon powder, water-retaining agent, haydite, the present invention can not only solve the problems, such as that building castoff is handled using discarded clay brick as regeneration lightweight aggregate to prepare light masonry mortar, and the gradual deficient situation of sand and stone resources can also be alleviated, and there is the effect of light thermal-insulation by crushing common brick as light masonry mortar prepared by aggregate, meet the policy of national energy-saving emission reduction.Meanwhile meet existing professional standard JGJ/T 70 using the light masonry mortar of formula production of the present invention《Building mortar basic performance tests method standard》Regulation.

Description

The light masonry mortar prepared using discarded clay brick
Technical field
The present invention relates to discarded construction material process fields, and in particular to a kind of lightweight prepared using discarded clay brick Masonry mortar.
Technical background
According to reports, China produced 20,000,000,000 m in total in past 50 years3The clay brick of left and right, and these clay bricks It will be discarded with removal, and account for about the 30%~50% of total amount of construction waste according to estimation.Meanwhile with domestic infrastructure Development, sand and stone resources are also increasingly deficienter.How building castoff is being solved with finding a stationary point in resource recycling, It is current urgent problem.
It can alleviate the sand and stone resources gradually political affairs of the situation of scarcity and national energy-saving emission reduction there is presently no a kind of Plan, and not only have light thermal-insulation effect, also have both sound absorption effect utilization discard clay brick preparation lightweight build sand by laying bricks or stones Slurry.
Invention content
The present invention be exactly in view of the above-mentioned problems, provide it is a kind of can alleviate sand and stone resources gradually deficient situation and The policy of national energy-saving emission reduction, and not only there is the effect of light thermal-insulation, clay brick is discarded in the utilization for also having both sound absorption effect The light masonry mortar of preparation.
In order to achieve the above objectives, the present invention uses following technical scheme.
The light masonry mortar prepared using discarded clay brick, including major ingredient, auxiliary material, it is characterised in that major ingredient grain size is 0.5~4.75mm, auxiliary material include cement, flyash, silicon powder, water-retaining agent, haydite, and each component mass percent meets following want It asks：Major ingredient 25%~45%, cement 15%~30%, flyash 2%~5%, silicon powder 0.3%~0.8%, water-retaining agent 0.01%~0.2%, Haydite 25%~45%.The cement preferred density is the portland cement of 3.0g/cm3.The flyash preferred density is 2.4g/ The Class F fly ash of cm3.Water-retaining agent active constituent >=92%, particle size need to meet 100 mesh sieve percent of pass >=95%.It is described The preferred hydroxypropyl methyl cellulose ether of water-retaining agent.The haydite is grain size 5~8mm clay haydites.
The present invention also provides a kind of methods for preparing light masonry mortar using discarded clay brick, include the following steps：First, It is prepared by major ingredient, discarded clay brick is crushed by movable crusher, sieves, clean, dry after screening particle size range be The regeneration clay brick aggregate of 0.5~4.75mm is spare as major ingredient；2nd, it feeds intake, by major ingredient, cement, flyash, silicon powder, pottery Grain is put into successively after metering system is weighed by bucket elevator to be stirred 60 seconds or more in advance in blender；3rd, spice, in step 2 into It went and adds in a certain amount of water-retaining agent in the powder stirred in advance, be stirred for 120 seconds or more.
The present invention can not only solve to build to give up using discarded clay brick as regeneration lightweight aggregate to prepare light masonry mortar The problem of gurry processing, and the gradual deficient situation of sand and stone resources can also be alleviated, and prepared as aggregate by broken common brick Light masonry mortar there is the effect of light thermal-insulation, meet the policy of national energy-saving emission reduction.Meanwhile matched using of the present invention The light masonry mortar just produced meets existing professional standard JGJ/T 70《Building mortar basic performance tests method standard》's Regulation.
Specific embodiment
The technical solution in the present invention is clearly and completely described with reference to specific embodiment, it is clear that described Embodiment be only part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ability Domain those of ordinary skill all other embodiments obtained without making creative work, belong to guarantor of the present invention The range of shield.
Embodiment one：
Weight calculation is weighed after major ingredient 400Kg, haydite 400Kg, cement 350Kg, flyash 50Kg, silicon powder 7Kg by bucket elevator successively It is stirred in advance 60 seconds in input blender, then adds in 0.15% water-retaining agent of total quality of material, be stirred for 120 seconds or more.
Embodiment two：
Weight calculation is weighed after major ingredient 400Kg, haydite 400Kg, cement 300Kg, flyash 50Kg, silicon powder 6Kg by bucket elevator successively It is stirred in advance 60 seconds in input blender, then adds in 0.12% water-retaining agent of total quality of material, be stirred for 120 seconds or more.
Embodiment three：
Weight calculation weigh after major ingredient 400Kg, haydite 400Kg, cement 260Kg, flyash 50Kg, silicon powder 5.4Kg by bucket elevator according to It is stirred in advance in secondary input blender 60 seconds, then adds in 0.10% water-retaining agent of total quality of material, be stirred for 120 seconds or more.
Using this formula production light masonry mortar water retention reach more than 88%, setting time between 3~9h, 2h Consistency loss late≤30%, meanwhile, it is respectively 1200Kg/m by one, two, three production sample surface drying density of embodiment3、1150Kg/ m3、1110Kg/m3, crushing strength be respectively >=15MPa, >=10MPa, >=7.5MPa, flexural strength be respectively >=4.0MPa, >= 3.5MPa、≥2.8MPa。
