Description
Technical field
The present invention relates to a kind of structure material, the in particular preparation method of a kind of sound barrier Fast Filling gravity mortar.
Background technology
Gravity mortar is the material of the adjustable superhigh intensity of a kind of performance and high flowability, relies on self gravitation filling voluntarily just can meet the mortar that grouting requires.Have that setting time is fast, good flowing properties, early strength high, anti-fatigue performance is good, defy severe cold the features such as heat, convenient and quick construction.Extensive use wind barrier base steel plate can be installed by filling, the installation filling of sound barrier base steel plate and the installation filling of mast base steel plate etc..All actively expand the gravity mortar research and development of superhigh intensity high flowability at present both at home and abroad, but still there are following technological difficulties: significantly high initial flow degree 1, cannot be obtained, the requirement of strength after causing constructional difficulties and construction cannot being ensured；2, cannot ensureing later stage fluidity retention, construction operable time is greatly shortened；3, significantly high early strength cannot be obtained and ensure that later strength continues to increase；4, cannot have adaptability good accordingly along with the change of seasonal temperature.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the preparation method of a kind of sound barrier Fast Filling gravity mortar, prepared gravity mortar early strength is high, fluidity is big.
The present invention is achieved by the following technical solutions, the present invention by weight, including ordinary cement 30～40 parts, sulphate aluminium cement 10～15 parts, 45～55 parts of aggregate, silicon ash 3～8 parts, early strength agent 0.5～1.0 part, retarder 0.1～0.5 part, water reducer 0.1～0.5 part.
One of optimal way as the present invention, described ordinary cement is intensity 52.5 grades and above Portland cement.
One of optimal way as the present invention, the intensity of described sulphate aluminium cement is more than 525 grades.
One of optimal way as the present invention, described aggregate is the particle diameter quartz sand less than 1.18mm continuous grading.
One of optimal way as the present invention, described early strength agent is that calcium formate prepares by weight 1:1 is composite with sodium nitrate.
One of optimal way as the present invention, described retarder is that sodium gluconate prepares by weight 2:1 is composite with Borax.
Described fiber is polypropylene fibre, can form the netted support effect of three-dimensional random distribution, make mortar be stopped in evolution at the micro-crack that the hardening initial stage is formed, it is difficult to develop further in mortar.Thus the fracture toughness of mortar can be improved, improve the anti-crack and anti-seepage performance of mortar, be mortar, concrete works cracking resistance, antiseepage, wear-resisting, the new type ideal material of insulation.
A kind of preparation method of sound barrier Fast Filling gravity mortar, by described ordinary cement, sulphate aluminium cement, aggregate, silicon ash, early strength agent, retarder, these powder stirrings of water reducer uniformly after, adding the water of powder weight 0.14～0.16 times, mechanical agitator can use after being sufficiently stirred for.
Portland cement is long as gravity packing material ubiquity setting time, the not high defect of early strength, it is impossible to fully meet the requirement of filling.This deficiency for Portland cement, adopt the sulphate aluminium cement that setting time is fast, early strength is high composite with it, add the additives such as high efficiency water reducing agent on this basis compound system is modified, the filling characteristic making Portland cement improves significantly, both improve mobility, take into account again setting time and strength characteristics preferably.Silicon ash is the unformed silicon oxide of high fineness, has higher pozzolanic activity, it is possible to hydrolysis product of cement CH is converted into CSH gel, promotes that intensity and degree of compaction improve, accelerates hydration rate, improve early strength.Silicon ash has adjustment viscosity concurrently, improves cohesiveness, reduces bleeding, improves the functions such as impervious, intensity and durability.Calcium formate and sodium nitrate, as a kind of additive, have acceleration hydrated cementitious, avoid in the winter time or construction rate of set crosses the problems such as slow when low temperature and moisture, improve the performance of mortar strength, it is possible to play certain minimizing effect.Sodium gluconate and Borax have good deferred action, it addition, sodium gluconate can effectively suppress chemical shrinkage, aquation initial stage sodium gluconate acts on due to absorption, complexation, moistening etc., accelerates C3The dissolving of A, has promoted the generation of Alt, suppresses C simultaneously3The aquation of S and the generation of CH, can effectively reduce the heat of hydration, delay the formation of structure.
The present invention has the advantage that compared to existing technology and adds water the mortar of the present invention after mix initial flow degree is more than fluidity after 360mm, 30min more than 300mm, and early strength is high, obtains the intensity more than 20MPa in 1～2h, and 28d intensity is more than 50MPa.Can completing to add the requirement of torsion, later strength not retraction, easy construction after mortar injection within a short period of time, simply, the stirring that adds water can use, and can construct when subzero temperature, and when subzero temperature intensity can sustainable growth, reach final utilization performance.
