preparation example Construction

[0032] The present invention also relates to a preparation method of the above-mentioned clear water mirror concrete, specifically comprising the following steps:

[0033] Step 10, sieving the artificial sand and stone fine aggregate, sieving the fine aggregate with a particle size of 0.16 to 50 mm, and drying it for later use;

[0034] Step 20, sieve the mineral admixture, and then dry it for later use;

[0035] Step 30. Mix the fine aggregate, cementitious material, chemical admixture, and mineral admixture, add water and stir, and finally put the evenly stirred mixture into the mold, and maintain and shape it; after reaching the set age, take off mold, that is, clear water mirror concrete.

[0036] Preferably, the mass percentages of the components in the chemical admixture to the total weight of the clear water mirror concrete material are: 0.82% to 0.90% of the water reducer, 0.96% to 1.4% of the cellulose, and 0.16% of the cellulose ether HPMC %~1.10% and redispersible...

Abstract

The invention provides a preparation method for clear water mirror surface concrete The concrete comprises, by weight, 75.20%-79.15% of fine aggregates, 14.2%-15.9% of binding materials, and 3.0%-3.9% of mineral admixtures. Chemical additives weigh 3.5%-4.7% of the binding materials. The preparation method is as follows. The artificial sandstone fine aggregates are sieved and dried, standby. The mineral admixtures are sieved and dried, standby. The fine aggregates, binding materials, chemical additives and mineral admixtures are mixed, stirred with addition of water, finally, the evenly-mixed mixture is put into dies, maintained and moulded. When reaching the setting age, the clear water mirror surface concrete is obtained after demoulding. The surface of the concrete is flat, bright and clean and the concrete has good mirror effects. The concrete is easy to clean, abrasion resistant and antifouling.

Description

【Technical field】 [0001] The invention relates to the field of building materials, in particular to a preparation method of clear water mirror concrete. 【Background technique】 [0002] Since the advent of Portland cement in 1842 and the appearance of reinforced concrete in 1850, the development of concrete has a history of more than 150 years. In the past, as an important building structure material, the mechanical performance evaluation of concrete occupied a dominant position in the entire concrete performance evaluation system, and then high-performance concrete (HPC) appeared. In recent years, green high-performance concrete (GHPC) has been proposed. Its purpose is to save resources, energy, and reduce damage to the environment. [0003] As a new type of architectural form, fair-faced concrete forms its unique aesthetic feeling with its fine and delicate texture, dense and nearly homogeneous texture, and is accepted by more and more architects. Fair-faced concrete has ...
