Embodiment 1

[0028] Embodiment 1: pumping agent of the present invention

[0029] The components of the fair-faced concrete pumping agent are calculated by weight percentage: sulfamate superplasticizer 30%; methyl silicone oil 0.1%; sodium gluconate 1%; hydroxypropyl methylcellulose 0.08%; water 68.82% . Each component of the clear-water concrete pumping agent of the present invention is a commercially available product, and the water is ground water.

[0030] The preparation method of clear-water concrete pumping agent: take the above-mentioned components according to the proportion, first add water into the mixer, and then add sulfamate high-efficiency water reducer, sodium gluconate, and hydroxypropyl methylcellulose into the mixer Stir in the medium for 30 minutes, add the weighed methyl silicone oil into the mixer and stir for 2 hours to obtain the clear-water concrete pumping agent product.

Embodiment 2

[0031] Embodiment 2: pumping agent of the present invention

[0032] The components of the clear-water concrete pumping agent are calculated by weight percentage: 30% of sulfamate superplasticizer; 0.3% of emulsified silicone oil; 2% of sodium tripolyphosphate; 0.05% of methyl cellulose; and 67.65% of water.

[0033] The preparation method of fair-faced concrete pumping agent is the same as embodiment 1.

Embodiment 3

[0034] Embodiment 3: pumping agent of the present invention

[0035] The components of the clear-water concrete pumping agent are calculated by weight percentage: 40% of sulfamate superplasticizer; 0.1% of methyl silicone oil; 3% of citric acid; 0.02% of hydroxyethyl cellulose; and 56.88% of water. The upper component is taken in proportion, and the preparation method is the same as in Example 1.

Abstract

The invention relates to the field of building materials and discloses an exposed concrete pumping agent and a preparation method thereof. The exposed concrete pumping agent comprises the following raw materials by weight percent: 30%-50% of sulfamate superplasticizer, 0.1%-0.5% of defoaming agent, 1.0%-3.0% of retarder, 0.02%-0.08% of water retaining agent and the balance of water. The preparation method comprises the following steps: after various raw materials are weighed according to weight percent, mixing and stirring the sulfamate superplasticizer, retarder and water retaining agent for30 minutes; and then adding the defoaming agent to stir for 2 hours so as to obtain the exposed concrete pumping agent. By using the exposed concrete pumping agent, the surface of the prepared concrete is smooth and has no honeycomb, pitting skin, holes, stress marks and pollution, and simultaneously the workability and flowability of the exposed concrete can be effectively improved, thus the exposed concrete pumping agent can be widely applied to building elevation decorations such as bridges, houses and the like.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a clear-water concrete pumping agent and a preparation method thereof. Background technique [0002] Concrete is one of the most important contemporary building materials. It is an artificial stone made of cementing materials, aggregates, aggregates and water prepared in a certain proportion, shaped by stirring and vibrating, and cured under certain conditions. Concrete usually refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate, mixed with water in a certain proportion, and then stirred, formed and cured. It is also called ordinary concrete. Concrete has the characteristics of abundant raw materials, low price, simple production process, high compressive strength, good durability, wide range of strength grades, etc., and is widely used in civil engineering. [0003] Clear-water concrete (As-cast Finish Concrete / B...
