Abstract
The invention relates to a diatomite modified cement and light high-strength concrete preparing method, including components in weight percent: ordinary Portland cement 47-89.5%, surface modified diatomite 10-50%, and additive 0.5-3%, feeding the prepared materials in a rough mixing machine and a fine mixing machine, so as to obtain the diatomite modified cement, then mixing and stirring the diatomite modified cement with sand, stone and water to obtain the light high-strength concrete. This concrete has lightness, high strength, good heat-insulating and -preserving effect, ability to resist UV radiation, wide use, ability to act as light wall material, light cement prefabricated part, bearing material, etc, able to be widely applied to high-rise architectures, storey architectures, industries in need of preserving heat, insulating heat and insulating sound and civil architectures.
Description
Affiliated technical field
The present invention relates to a kind of diatomite modified cement and light high strength concrete preparation technology.
Background technology
Present light weight concrete has two kinds of preparation methods, and a kind of method is to adopt light-weight aggregate, and light-weight aggregate divides two classes, and a class is natural light-weight aggregate, processes through fragmentation with natural porous rock, as float stone, coal gangue; Another kind of is artificial lightweight aggregate, burn to expand or sinters vesicular structure into and get through excessive temperature with clay, shale, perlite etc., as lytag, coal gangue haydite, leca, haydites of book structure and pearlstone, expanded slag pearl, cinder etc.Its intensity of the light weight concrete of light-weight aggregate manufacturing depends on the intensity of gathering materials, because light-weight aggregate intensity is lower, so the gained concrete strength is not high, and the water-intake rate of light-weight aggregate is big, concrete mixing is difficulty relatively, and when the needs high-strength lightweight concrete, bulk density is higher.Another kind method is a cellular concrete, adopts air and whipping agent to make, and its intensity is very low, also is difficult to satisfy the load-bearing requirement, and the reinforcing bar of being joined in the cellular concrete is particularly even more serious under humidity height or the environment at alternation of wetting and drying than easy-to-rust.
Summary of the invention
The preparation technology and a kind of light high strength concrete preparation technology that the purpose of this invention is to provide a kind of diatomite modified cement, this concrete is a lightweight, insulation, have good heat-insulation and heat-preservation, ultra-violet radiation resisting effect, and the intensity height, can be widely used in Highrise buildings, floor building, need insulation, heat insulation, sound damping is industrial and covil construction.
The object of the present invention is achieved like this: this diatomite modified cement preparation technology, form and be by weight percentage: 47～89.5% ordinary Portland cements, 10～50% surface modification diatomite, 0.5～3% admixture batching, the material for preparing by raw material storage, fed in the thick mixer by belted electronic balance, is fed and promptly gets various diatomite modified cements in the smart mixer.
This diatomite modified cement preparation technology, described surface modification diatomite is that diatomite is handled gained through surperficial hydrophobic.
A kind of preparation technology of light high strength concrete is characterized in that: the diatomite modified cement mixes stirring again and gets final product with an amount of sand, stone, water.
Light high strength concrete of the present invention has following effect:
1, light-duty, unit weight is 500～1200kg/m
3, can be used for Highrise buildings;
2, being coated in exterior wall has good heat insulation and preservation effect, and thermal conductivity is 0.04～1.0W/m.k, can also ultra-violet radiation resisting;
3, intensity height, with the intensity height of the lightweight concrete material under the density conditions, ultimate compression strength was 10～35MPa to intensity in 28 days, can be used as structural material at present;
4, of many uses, can be used as light wall material, light cement pre-member, load-bearing material etc., can be widely used in Highrise buildings, floor building, need insulation, heat insulation, sound damping is industrial and covil construction.
Embodiment
Cement manufacture plant is by raw material storage, belted electronic balance, feeding machine, thick mixing machine, smart mixing machine, cement storage warehouse is formed, diatomite through surperficial hydrophobic handle surface modification diatomite, will (by weight percentage) 42.5 ordinary Portland cements 80%, 19% surface modification diatomite, the admixture batching that 1% chlorine flower calcium hardening accelerator and water reducer are made, the material for preparing is passed through raw material storage, feed in the thick mixer by belted electronic balance, feed and promptly get the diatomite modified cement in the smart mixer, gained cement mixes with 32% water and stirs that can to make unit weight be 850kg/cm
3, CL30 (28 days intensity is 30MPa) light high strength concrete, thermal conductivity is 0.062W/m.k.
Claims (3)
1, a kind of diatomite modified cement preparation technology, it is characterized in that forming and be by weight percentage: 47～89.5% ordinary Portland cements, 10～50% surface modification diatomite, 0.5～3% admixture batching, the material for preparing by raw material storage, fed in the thick mixer by belted electronic balance, is fed and promptly gets the diatomite modified cement in the smart mixer.
2, diatomite modified cement preparation technology as claimed in claim 1 is characterized in that: described surface modification diatomite is that diatomite is handled gained through surperficial hydrophobic.
3, a kind of preparation technology of light high strength concrete is characterized in that: the diatomite modified cement mixes stirring again and gets final product with an amount of sand, stone, water.
