Abstract
The invention relates to a concrete accelerator. The concrete accelerator is prepared by mixing, by weight, 10-15 parts of fatty acid methylolamide, 8-12 parts of a water-soluble calcium salt, 3-7 parts of sodium carbonate, 5-10 parts of fly ash, 3-7 parts of blast furnace gas mud, 4-8 parts of silicon powder, 10-15 parts of aluminum oxygen chamotte powder, 6-10 parts of calcium formate, 5-10 parts of quicklime and 7-12 parts of zinc sulfate. The concrete accelerator has the following advantages: 1, the setting time is short: the initial setting time is 1-5min, the final setting time is 5-10min, and the suitable mixing amount is 3-5% of the amount of a gelling material; 2, the alkali metal content is smaller than 1%, and the accelerator is nontoxic, tasteless and irritant; 3, the fineness meets a condition that the proportion of residues on a 80[mu]m sieve is smaller than 10%; 4, the early stage strength of a sprayed concrete is high, and the 28d age compressive strength retention rate reaches 80-100%; and 5, the cohesiveness of a spray material is good, the spray material has no corrosion effect on steel bars, the one-time spraying layer is thick, the thickness of a spray arch can reach 130mm, and the thickness of a spray wall can reach 200mm or more.
Description
Technical field
The present invention relates to a kind of Hardenfast.
Background technology
Concrete time of coagulation is longer, and the initial set more than 5 minutes of general needs, final set in more than 10 minutes, produces certain intensity in more than 1 hour.The concrete that will not solidify for a long time easily causes the carrying out of financial loss and normal social activity, and, will not solidify for a long time and easily cause the concrete chemical composition being harmful to human body to be volatilized for a long time, affect the healthy of people.Therefore, a kind of accelerating chemicals of concrete quick solidification that can make is provided to be the current task of top priority.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of Hardenfast.
Described a kind of Hardenfast, it is characterized in that being mixed by the raw material of following weight part: fatty acid methyl alcohol amide 10-15, water-soluble Ca salt 8-12, sodium carbonate 3-7, flyash 5-10, gas mud 3-7, silica flour 4-8, aluminum oxide clinker powder 10-15, calcium formiate 6-10, unslaked lime 5-10, zinc sulfate 7-12.
Described a kind of Hardenfast, it is characterized in that being mixed by the raw material of following weight part: fatty acid methyl alcohol amide 12-14, water-soluble Ca salt 9-11, sodium carbonate 4-6, flyash 7-9, gas mud 4-6, silica flour 5-7, aluminum oxide clinker powder 12-14, calcium formiate 7-9, unslaked lime 6-8, zinc sulfate 9-11.

Beneficial effect of the present invention is:
1, time of coagulation is short: initial set 1 ~ 5min, final set 5 ~ 10min, and moderate dosage is 3-5% of gel material content;
2, alkali metal content <1%, nontoxic, tasteless, non-stimulated;
3, fineness: 80 μm of hole sizers, screenings is less than 10%;
4, jetting cement early strength is high, and its, ultimate compression strength storage rate reached 80-100% in 28 day length of time;
5, material spray cohesiveness is good, and to the effect of reinforcing bar non-corroding, improve anti-penetration grade, condensation is fast, and one time spray-up is thick, and spray arch can reach 130mm, and spray wall can reach more than 200mm.
