Abstract
The invention discloses an application of a PC component concrete nutrient-enhancing-free water reducing agent. The invention applies the polycarboxylate water reducer to the concrete for PC components. Compared with the original concrete, the application of the polycarboxylate water reducer in the PC component concrete has the advantages that the hardening speed is high, the early strength is high, the PC component laminated slab is taken off in advance one day, the heating steam curing process is avoided, the curing cost is reduced, and the benefit is improved.
Description
Technical Field
The invention relates to the technical field of building materials, in particular to an application of a PC component concrete raising-free water reducing agent.
Background
After the concrete is doped with the water reducing agent, the water reducing agent has a sufficient dispersing effect on cement particles, so that the fluidity of the concrete is improved, and the workability of the concrete is enhanced; under the condition of keeping the original workability, the water consumption can be reduced, and the strength of the concrete is improved. Due to the application of the water reducing agent, the water reducing effect of the water reducing agent can greatly reduce the water-cement ratio of the concrete, thereby improving the strength of the concrete.
Disclosure of Invention
The invention aims to provide an application of a PC component concrete nutrient-enhancing-free water reducing agent for solving the technical problems.
The invention adopts the following technical scheme for realizing the purposes:
the invention applies the polycarboxylate water reducer to the concrete for PC components.
The beneficial effects of the invention are as follows: compared with the original concrete, the application of the polycarboxylate water reducer in the PC component concrete has the advantages that the hardening speed is high, the early strength is high, the PC component laminated slab is taken off in advance one day, the heating steam curing process is avoided, the curing cost is reduced, and the benefit is improved.
Description of the embodiments
The following description of the embodiments of the present invention will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention takes the C30 concrete design mixing proportion as an example, and the specific mixing proportion and the dosage are as follows:
| project | Quantity (kg) |
| Cement and its preparation method | 300 |
| Fly ash | 45 |
| Mineral powder | 55 |
| 1-5 cobbles | 290 |
| 1-2 stone | 745 |
| Coarse sand | 80 |
| Middle sand | 150 |
| Fine sand | 520 |
| Additive (polycarboxylate water reducer) | 10 |
| Water and its preparation method | 170 |
The invention improves the dosage of the water reducer, reduces the water-cement ratio and has good dispersion performance. The invention has the advantages of improving the early strength and the later strength and the durability of the concrete, along with good adaptability to the quality of the cement, improving the workability of the concrete, facilitating the control of the process and having the function of reducing water. The cast concrete can reach 75% of the design strength of C30 after 24 hours, and the PC component laminated slab can be lifted and taken off one day later, so that the steam curing process is saved, the steam curing cost is greatly reduced, and the efficiency is improved.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
