Abstract
The invention relates to a cement additive produced by replacing an active material with an inert material. The cement additive is characterized by comprising 8-10 parts of anion inert materials, 1000 parts of purified water and 1-5 parts of plasticizer, namely DOP (Dioctyl-Phthalate). During a preparing process, the anion inert materials and the purified water are slowly and uniformly stirred. After the temperature is increased to 90 DEG C and the temperature is kept for 8 hours, the plasticizer, namely DOP is added. The additive is added into concrete for preparing cement and is capable of increasing the impact resistance, abrasion resistance and anti-permeability waterproof property of the cement. The attrition rate of the cement is reduced by 44.6%.
Description
[technical field]
The present invention relates to a kind of concrete admixture, be specifically related to a kind of inert material and replace active material to produce cement additive.
[background technology]
Use concrete that particular requirement is arranged when special engineerings such as motorway, airfield runway, bridge road surface are built, generally its slump, ultimate compression strength, folding strength, shrinking percentage and rate of wear are all had very high requirement.And motorway that traditional mortar concrete is built or airfield runway etc. are frequently used by HS such as vehicle or aircraft or high external pressure; It collapses easily; Surface abrasion is serious; Cause pavement roughness to influence the normal use of motorway or airfield runway as time passes, so just need the later period maintenance maintenance to increase its cost.
[summary of the invention]
For solving above deficiency; The present invention provides a kind of inert material to replace active material to produce cement additive; This admixture utilizes inert material to replace active material Z 150PH (PVA model 1788) to be added in the construction concrete such as building airfield runway or motorway, increases its shock resistance and burnish resistance and impervious water resistance.
Technical problem to be solved by this invention is: the concrete of prior art can't satisfy motorway or airfield runway etc. has particular requirement to the concrete slump, ultimate compression strength, folding strength, shrinking percentage and rate of wear.
The present invention the technical scheme that will adopt be: inert material replaces active material to produce cement additive and it is characterized in that negatively charged ion inert material 8-10 part; 1000 parts of pure water; Softening agent (DOP) 1-5 part; The mixing of negatively charged ion inert material and pure water stirs at a slow speed in the time of preparation, and 90 degree are heated and constant temperature added softening agent (DOP) in 8 hours then.
Inert material replaces active material to produce cement additive and replaces active material Z 150PH (PVA) through the negatively charged ion inert material; Use negatively charged ion inert material 8-10KG, add pure water 1000KG and stir at a slow speed then, it is mixed; Through the heating unit Heating temperature is 90 degree; And kept 90 degree constant temperature 8 hours, and adding softening agent (DOP) 1-5KG then, it can excite the activity of negatively charged ion inert material.This admixture adds in the cement by 2% of cement quality and gets final product.
Beneficial effects of the present invention: the additive added to the prepared concrete Quan, can increase its impact resistance, abrasion resistance and water impermeability, and its wear rate decreased 44.6%.
Further understand characteristic of the present invention and technology contents for making, see embodiment of the present invention for details, yet institute's embodiment is only for reference and explanation usefulness, is not to be that the present invention is limited.
[embodiment]
Below in conjunction with specific embodiment the present invention is elaborated:
Embodiment 1, and inert material replaces active material to produce cement additive and replaces active material Z 150PH (PVA) through the negatively charged ion inert material, uses negatively charged ion inert material 8KG; Adding pure water 1000KG stirs at a slow speed then; It is mixed, and is 90 degree through the heating unit Heating temperature, and keeps 90 degree constant temperature 8 hours; Add softening agent (DOP) 1-5KG then, it can excite the activity of negatively charged ion inert material.This admixture adds in the cement by 2% of cement quality and gets final product.
Embodiment 2, and inert material replaces active material to produce cement additive and replaces active material Z 150PH (PVA) through the negatively charged ion inert material, uses negatively charged ion inert material 9KG; Adding pure water 1000KG stirs at a slow speed then; It is mixed, and is 90 degree through the heating unit Heating temperature, and keeps 90 degree constant temperature 8 hours; Add softening agent (DOP) 1-5KG then, it can excite the activity of negatively charged ion inert material.This admixture adds in the cement by 2% of cement quality and gets final product.
Embodiment 3, and inert material replaces active material to produce cement additive and replaces active material Z 150PH (PVA) through the negatively charged ion inert material, uses negatively charged ion inert material 10KG; Adding pure water 1000KG stirs at a slow speed then; It is mixed, and is 90 degree through the heating unit Heating temperature, and keeps 90 degree constant temperature 8 hours; Add softening agent (DOP) 1-5KG then, it can excite the activity of negatively charged ion inert material.This admixture adds in the cement by 2% of cement quality and gets final product.
Is standard in Southeast China University's material laboratory detected result according to Jiangsu east large-engineering detection technique ltd by JGJ-2000, GB/T50080-2002, GB/T50081-2002, TGE30-2005:
Yet the preferable feasible embodiment of above-mentioned only the present invention, non-so limitation protection domain of the present invention is done various distortion or is applied mechanically all within this technical scheme protection domain according to the foregoing description.
