Abstract
The invention discloses white self-compacting C40-pumping fair-faced concrete including the components of: 350-430 kg/m<3> of cement, 50-80 kg/m<3> of slag micropowder, 790-830 kg/m<3> of quartz sand,5-6 kg/m<3> of additives, 155-165 kg/m<3> of blending water, 5-8 kg/m<3> of TiO2 pigment and 900-940 kg/m<3> of crushed andesite rock. The concrete has the performances of high flowability and self-compacting effect of regular self-compacting concrete and has a pure-white appearance that does not change along with time. The product also has the surface performances of fair-faced concrete, is lessin bubbles and has homogeneous color, so that the product has great application value in the field of decorative concrete. The concrete can serve as a structural concrete base material in an integrated shaping manner, is free of decoration on concrete surface, can save coatings and reduce manpower cost, and satisfies the green-construction idea in our country.
Description
Technical field [0001] The invention belongs to the field of building materials and relates to a white, high-strength, self-compacting mass-produced fair-faced concrete, specifically a white self-compacting fair-water C40 pumping concrete. Background technique [0002] With the continuous development of the economy, the requirements for environmental protection and vision of buildings are increasing. Following this trend, fair-faced concrete technology has developed rapidly. With its advantages of safety, cleanliness, beauty, easy cleaning, and durability, it has become a large-scale public building. Preferred. However, the color of traditional fair-faced concrete is relatively single, mainly based on the original color of concrete. Many architectural designs began to put forward more requirements for the decorative surface of the outer wall. Although the traditional exterior wall decorative hanging boards are rich in shapes, they cannot bring out the natural and rustic feeling...
