Abstract
The invention discloses a kind of preparation method of efficiency slow release type light skeletal, comprise following preparation process: (1) drills through the aperture that diameter is 2-6mm on light skeletal, and powdered fertilizer is filled in aperture; (2) 30-75g cement clinker, 2-7g trolamine, 0.5-2g water reducer, 10-20g water and 15-30g gypsum mix and blend are made homogeneous slurry; (3) light skeletal of filling fertilizer is soaked in 10-20 in slurries to take out after second, and natural air drying, obtain efficiency slow release type lightweight concrete for plant growth aggregate.Aggregate prepared by the present invention and concrete substrate consistency good, affect concrete strength and service life hardly; Under the regulation and control of aggregate case-hardening body, the efficiency slow release of its inner filling fertilizer is respond well; Raw material is easy to get, and technique is simple.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of preparation method with the lightweight polyphenyl granulated aggregate of efficiency slow release effect.
Background technology
Under the dual function of artificial destruction and natural disaster, be described as " kidney of the earth " Wetlands ecosystems and be heavily polluted and eutrophication, Wetland Area is atrophy significantly, and wetland species fail.Lightweight concrete for plant growth realizes its special structure and fuction by the screening of self composition material, optimum preparation condition, can be used for wet land protection engineering.But make granular polystyrene surface and the bad adhesion of gelling material of aggregate, cause concrete for plant growth intensity low, service life serious curtailment.Meanwhile, fertilizer is directly mixed concrete for plant growth and not only can reduce concrete strength, and the alkaline matter that discharges of concrete hydrating can destroy the release membranes on fertilizer top layer, causes fertilizer efficiency to run off fast.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of efficiency slow release type light skeletal.The aggregate prepared by the method is due to top layer parcel hardening of cement body, good with concrete substrate consistency; Inner fertilizer of filling efficiency slow release under the regulation and control of case-hardening body is respond well.
Technical scheme of the present invention is as follows:
A preparation method for efficiency slow release type light skeletal, comprises following preparation process:
(1) on light skeletal, drill through the aperture that diameter is 2-6mm, and powdered fertilizer is filled in aperture;
(2) 30-75g cement clinker, 2-7g trolamine, 0.5-2g water reducer, 10-20g water and 15-30g gypsum mix and blend are made homogeneous slurry;
(3) light skeletal of filling fertilizer is soaked in 10-20 in slurries to take out after second, and natural air drying, obtain efficiency slow release type lightweight concrete for plant growth aggregate.
Light skeletal of the present invention is granular polystyrene, and diameter is between 30-50mm; Described cement is aluminosulfate cement, and its specific surface area is between 380 ~ 420m
2/ Kg; Described water reducer is polycarboxylate water-reducer.
Outstanding advantages of the present invention is:
(1) aggregate prepared by the present invention and concrete substrate consistency good, affect concrete strength and service life hardly;
(2) efficiency slow release of its inner filling fertilizer under the regulation and control of case-hardening body of the aggregate prepared by the present invention is respond well;
(3) raw material is easy to get, and technique is simple.
