Abstract
The invention provides a high-strength concrete building block, which comprises polystyrene granules, fibers, polymers and a water reducing agent, wherein the particle sizes of the polystyrene granules are 2-6mm and the apparent density of the polystyrene granules is 15kg/m<3>; the fibers are made from vegetable sisal hemp and polypropylene fibers, the lengths of fibers are controlled to be within 10mm and 15mm, and according to the common specification of the adding amount of concrete, 1kg/m<3> of the sisal hemp, as well as 1kg/m<3> of polypropylene and 0.8kg/m<3> of polypropylene are respectively adopted in experiments; the polymers are prepared from water-soluble epoxy resin and a curing agent according to the ratio of 4 to 1, the adding amount of the water-soluble epoxy resin and the adding amount of the curing agent are respectively 0.5% and 0.125% of the doping mass of a cementing material; the water reducing agent is an MN-II type water reducing agent, wherein the water reducing rate is 20% and the participating-in amount is 0.5%. The high-strength concrete building block is high in strength and is relatively slightly influenced by an external environment.
Description
Technical field
The present invention relates to a kind of strong concrete building block, belong to technical field of civil engineering.
Background technology
The general quality that existing concrete segment structural strength is high is comparatively hard, and in the middle of the making in later stage, due to the impact by temperature and humidity, the quality after its block is often not as people's will.If there is the natural disasteies such as earthquake, comparatively speaking, the structural strength ability resisting external force cannot meet international standard requirement.Therefore, how can study a kind of strong concrete building block, less by external environment influence, it is the problem that the present invention will study that intensity can reach standard.
Summary of the invention
The invention provides a kind of strong concrete building block, intensity is high, less by external environment influence.
For solving above technical problem, the invention provides following technical scheme: comprising: granules of polystyrene, particle diameter is 2-6mm, and apparent density is 15kg/m
3; Fiber: adopt vegetalitas sisal hemp and polypropylene fibre; Staple length controls between 10mm-15mm, and according to addition general in concrete regulation, sisal hemp 1 kg/m is adopted in this experiment
3, polypropylene 1 kg/m
3with 0.8 kg/m
3; Polymkeric substance: adopt water compatible epoxy resin and in conjunction with solidifying agent in 4:1 ratio use water compatible epoxy resin to be gelling material admixture quality 0.5%, solidifying agent is 0.125%; Water reducer: be MN-II type water reducer, water-reducing rate 20%, participation amount is 0.5%; Properties-correcting agent: addition content is 6%;
Exciting agent: adopt industrial anhydrous Na
2sO
4, addition content is 5%; Sand adopts degree of being modulus to be 2.7, and glue sand is than being 1:2; Water cement ratio 0.35; Wherein cement: breeze: flyash: sand: water=2:1:1:8:1.4.
This strong concrete building block that the present invention relates to, intensity is high, less by external environment influence.
