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...

[0048] A preparation method of clear water mirror concrete, specifically comprising the steps of:
[0049] 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;
[0050] Step 20, sieve the mineral admixture, and then dry it for later use;
[0051] Step 30, 4598.3g of fine aggregate, 1692.3g of cementitious material, chemical admixture (the specific weight of each component is as follows: 24g of cellulose, 20g of cellulose ether HPMC, 16g of redispersible latex powder, 14g of water reducing agent, defoaming 5.23g of colorant, 320g of coloring agent) and 415.3g of mineral admixture are mixed, and 780g of water is added to stir, and finally the well-stirred mixture is put into the mold and cured; Clear water mirror concrete.
[0052] The clear water mirror concrete product obtained above has smooth appearance, obvious mirror effect, and shrinkage value of 1.23%; 28d compressive...
