Description
Technical field
The present invention relates to building material fields, and in particular to a kind of concrete brick and preparation method thereof based on shell..
Background technology
It is concrete to be applied to the primary building material of structure in China's building, and rubble is its main coarse aggregate, rubble
Exploitation needs to expend a large amount of human and material resources, and there are security risks for exploitation rubble, the safety accident brought because exploiting rubble
Very much, in addition with the increase of building amount, rubble resource increasingly consumes.
With the fast development of China's shellfish culture and processing industry, a large amount of waste shells are produced every year.Ministry of Agriculture's fishery
Office's statistical data shows that China's shellfish yield in 2016 is 1447.36 ten thousand tons.Shell is considered as reluctant useless for a long time
Gurry, the overwhelming majority are discarded in seabeach or roadside etc..Residual meat on shell is easy to multiply mosquitos and flies, and day with high temperature is unpleasant according to lower generation
Foul smell, ambient enviroment and residents ' health are caused and seriously threatened, it has also become coastal area environmental problem urgently to be resolved hurrily.
The application technology as the second resource of waste shell includes mainly as soil conditioner, adsorbent, catalysis both at home and abroad at present
Agent, biologic packing material etc., however these are higher using technical fee to shell, large-scale promotion application is not easy, and can not largely be disappeared
Consume waste shell.Therefore waste shell is substituted into part rubble, is used as the coarse aggregate of concrete, turns waste into wealth, saved limited
Natural resources is particularly important.
Invention content
The purpose of the present invention is to provide it is a kind of it is light, intensity is high, thermal and insulating performance is good, and can efficiently use useless
Abandon the concrete brick and preparation method thereof of shell.
In order to realize that above-mentioned target, the present invention adopt the following technical scheme that：A kind of concrete brick based on shell, with weight
Part meter is measured, the concrete brick includes the raw material of following weight mixing：200-500 parts of cement, 200-700 parts of stone, shell
100-300 parts, 500-700 parts of sand, 0.5-5 parts of foaming agent, 150-300 parts of water is high-effect water-reducing agent 0.5-3 parts, described
The coarse aggregate of concrete brick is made of the shell of the stone of volume fraction 50% and the inside filled and process of volume fraction 50%.
Preferably, the shell is snail shell, and the grain size of snail shell is 10-25mm.
Preferably, the cement is the Portland cement of defined in GB175-2007 standards.
Preferably, the high-performance water reducing agent is polycarboxylate dehydragent.
Preferably, the dry moisture content of the saturation plane of the sand is 0.8%, meets the requirement of JGJ52 standards.
A kind of preparation method of the concrete brick based on shell, this method include following preparation process：
S1,0.5-5 parts of foaming agents are foamed by high pressure, and by pressure injection, foaming agent is generated foam-filled
Enter in 100-300 parts of shells；
S2, sand and 200-500 by 100-300 parts of the shells of inside filled and process, 200-700 parts of stone, 500-700 part
The cement of part sequentially adds in blender, and dry-mixed 60s makes each material be uniformly mixed；It is molten to weigh 0.5-3 parts of high-effect water-reducing agent
Solution is poured into 150-300 parts of water in mixed material, and 3min is stirred；
S3, molding：Slurry pours into standard module, and slight vibration is closely knit, is pruned the extra slurry of die surface simultaneously with spatula
It smoothes out；
S4, hardening maintenance：The test specimen of forming is placed in thermostatic chamber, maintenance demould for 24 hours, both standard-sized concrete
Brick.
The invention has the beneficial effects that：The waste shell for being filled with foam is replaced into part rubble, is used as concrete
Coarse aggregate, that the present invention is based on the concrete bricks of shell is light, intensity is high, also has good thermal and insulating performance, change give up into
Also the resource consumption of natural rubble is greatly saved while precious, can be widely applied to energy saving building.
