Problems solved by technology

[0002] Due to the current requirements for commercialization and high performance of concrete, fluidized and high-strength concrete has become the main direction of concrete technology development today. Ordinary concrete made of wood-calcium causes construction difficulties, which affects the popularization and application of high-strength concrete, especially in commercial concrete and pumped concrete.
[0003] At present, most manufacturers simply mix ordinary air-entraining agents, retarders and carriers to prepare plastic-retaining agents. This type of plastic-retaining agent can achieve a certain plastic-retaining effect, but it is far from the requirements of high-strength and high-performance concrete. , there is still a big gap

Embodiment 1

[0021] First mix 1 part (parts by weight, the same below) of boric acid and 14 parts of lactone, stir well to obtain the mixture, then add 8 parts of honey, 28 parts of rock sugar, 2 parts of ethyl acetate, and 2 parts of ferrous sulfate to the above-mentioned In the mixture, finally add 45 parts of water to mix, and after stirring evenly, a high-strength and high-retaining plastic plastic retaining agent for concrete is obtained, and the prepared admixture (serial number 1) and ordinary plastic retaining agent (serial number 2) are added according to 0.05% of the quality of the concrete adhesive Into the concrete mixture, and carry out comparative experiment with the concrete (serial number 3) that does not mix plastic retaining agent, experimental result is as table 1:

[0022] Table 1

[0023]

[0024] As can be seen from Table 1, the concrete slump loss of the product of this embodiment is very small, while the concrete with common plastic retaining agent and the concre...

Embodiment 2

[0026] First mix 3 parts of boric acid and 10 parts of lactone, stir well to get the mixture, then add 10 parts of honey, 20 parts of rock sugar, 3 parts of ethyl acetate and 2 parts of ferrous sulfate to the above mixture in turn, and finally add 52 parts Mix with water, stir evenly to prepare high-strength and high-retaining plastic plastic retaining agent for concrete, add the prepared admixture (serial number 1) and common plastic retainer (serial number 2) to the concrete mixture by 0.05% of the quality of the concrete adhesive, And carry out contrastive experiment with the concrete (serial number 3) that does not mix plastic retaining agent, experimental result is shown in Table 2:

[0027] Table 2

[0028]

[0029] As can be seen from Table 2, the concrete slump of the product of this embodiment has no loss substantially, while the concrete with ordinary plastic retaining agent and the concrete without plastic retainer have a slump of 10 mm and 50 mm in 1 hour, so T...

Embodiment 3

[0031] First mix 5 parts of boric acid and 7 parts of lactone, stir well to get the mixture, then add 14 parts of honey, 12 parts of rock sugar, 6 parts of ethyl acetate and 6 parts of ferrous sulfate to the above mixture in turn, and finally add 50 parts of mixed with water, and stirred evenly to prepare a high-strength and high-retaining plastic plastic retaining agent for concrete, the prepared admixture (No. 1) and common plastic retaining agent (No. 2) were added to the concrete mixture by 0.05% of the quality of the concrete adhesive , and compared with the concrete (No. 3) without plastic retaining agent, the experimental results are shown in Table 3:

[0032] table 3

[0033]

[0034] As can be seen from Table 3, the concrete slump loss of the product of this embodiment is very small, while the concrete with ordinary plastic retaining agent and the concrete without plastic retainer have a slump of 10 mm and 50 mm in 1 hour, so The plastic retaining agent of the pro...

Abstract

The invention discloses a high-strength and high-plastic retaining ability concrete plastic retaining agent and an application method of the plastic retaining agent. The plastic retaining agent is prepared by compounding 1-5 parts of boric acid, 7-15 parts of internal ester, 10-30 parts of crystal sugar, 7-15 parts of honey, 2-6 parts of ethyl acetate with 1-6 parts of ferrous sulfate. The plastic retaining agent is high in strength and plastic retaining ability and is especially suitable for high-strength concrete, commercial concrete and pump concrete.

Description

technical field [0001] The invention relates to a concrete admixture, in particular to a high-strength and high-plasticity plastic-retaining agent for concrete and a use method thereof. Background technique [0002] Due to the current requirements for commercialization and high performance of concrete, fluidized and high-strength concrete has become the main direction of concrete technology development today. Ordinary concrete made of wood-calcium causes construction difficulties, which affects the popularization and application of high-strength concrete, especially the application in ready-made concrete and pumped concrete. [0003] At present, most manufacturers simply mix ordinary air-entraining agents, retarders and carriers to prepare plastic-retaining agents. This type of plastic-retaining agent can achieve a certain plastic-retaining effect, but it is far from the requirements of high-strength and high-performance concrete. , there is still a big gap.
