Q:Iron ore waste rock can do building materials? You said SiO2 content of more than 65%, that is less than 65% sulfur can be used? Thank you!

Waste materials production of building materials, different building materials on the siliceous materials have technical quality requirements: 1) chemical composition requirements of China's silicate construction products of silicon raw materials chemical composition requirements: SiO2 ≥ 65%, Fe2O3 <15% MgO <5%, Na2O, K2O <2

Q:I said is built after the problem added: gray is not the color of cement mortar?

First, look at the color, lime mortar is white, mixed mortar is gray; Second, the test strength, the strength of lime mortar than the mixed mortar strength is much lower, generally not as good as your nails hard

Q:Measured the actual density of the concrete mixture for the 2450 attackers Ju Ju-hui angle to carry hair kg / m3. Such as site sand moisture content of 2.5%, stone moisture content of 0.5%, seeking construction mix. More

. Calculate the compounding ratio: 3.1 + 1.86 + 6.24 + 12.4 = 23.6 cement = (3.1 / 23.6) x 2450 = 322 water = (1.86 / 23.6) x 2450 = 193 sand = (6.24 / 23.6) x 2450 = 648 stone = (12.4 / 23.6) × 2450 =, construction with the attackers to play the trickle than the amount of cement than the amount of cement = 322 sand = 322 × (1 + 2.5%) = 330 stone = 1287 × (1 + 0.5%) = 1293 Water = 193- (330-322) - (1293-1287) = 179 Unit: kg / m?

Q:What is cracked mortar? What is the specific inside to participate in the material?

Anti-cracking mortar refers to the wall insulation energy-saving construction, in the insulation mortar construction, the application of a layer of anti-cracking effect of the special mortar, the general construction also need to add a layer of "alkali-resistant mesh cloth" Are the manufacturers produce finished products, in the field of mixing or ready to mix can be used. The main role is to prevent cracking and strengthen with the grass-roots storage pile stalk to fly the braids when the sowing the strength of the river, to prevent hollowing, delamination and surface layer (such as tiles) bonding is not strong, off and so on.

Q:What is the reason for the concrete from the skin? How to handle

Match the design is no problem, then the scene is the water caused by the concrete surface of the water-cement ratio is too large or over the earthquake with the ratio of the problem: the sand rate is too large
