Q:What is the difference between the new exterior wall decoration material and the real stone paint?

Real stone paint is decomposed resin emulsion sand wall-like construction of the scope of paint, only the paint used in the aggregate gradation and over the color of sand paint is more reasonable, more rich color, more realistic shape, more sophisticated construction methods, the use of more In general, the stain resistance is better than the color of the sand

Q:What is the bulk density of the sandy soil, the uniform load of the ground, the internal friction angle of the soil and the cohesion? Hope master quickly answer. The

Compaction after water stability, high strength, small capillary effect

This is a problem to be solved Your answer is adopted after the system will be rewarded 20 (wealth value + experience value) + problem bonus 30 (wealth value + experience value) and said: This is a problem to be solved

Q:. known to be adjusted by the mixing of concrete, a variety of materials, the amount of mixing materials: 4.5kg cement, water 2.7kg, sand 9.9 Hai Fu and Yan Gu Feng off the auxiliary kg, gravel 18.9kg. The apparent density of the concrete mixture was measured to be 2400 kg / m3. try to calculate the amount of various materials per cubic meter of concrete. If the construction site sand moisture content of 4%, stone moisture content of 1%, seeking construction mix. If you do not mix and match, directly to the laboratory with the use of construction in the field, the actual mix of concrete how to change? What is the effect on the strength of concrete? (Using 32.5 grade slag cement). Very urgent ah to the details of the process will be able to leave the best! Thank you! The The The The The The The The The The The The The More

(4.5 + 2.7 + 9.9 + 18.9) /2400 = 0.015m. 4.5: (2.7-9.9 * 4% -18.9 * 1%): 9.9 * (1 + 4% ): 18.9 * (1 + 1%) . the actual amount of sand and gravel is less lead to less than the number of concrete per set of concrete caused by the actual use of concrete than the design of the waste of cement

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

Anti-cracking surface mortar is a new type of anti-cracking dry powdery thin mortar made of Portland cement, fine fine aggregate, various kinds of polymer materials, additives and anti-cracking rental according to certain ratio. Product performance: . good bond strength, good crack resistance, high system security. . water retention is strong, there is a good anti-slip. . there is excellent flexibility, anti-freeze-thaw, anti-cracking, good weather resistance. . low water absorption, shrinkage is small. Product quality in line with "expansion polystyrene board thin plaster external wall insulation system" (JG149) standard

Q:Who can know the proportion of the building multi-storey building materials, steel, cement, red brick, sand and the percentage of each.

. steel: 40 ~ 75KG / square meter (multi-layer content is low, high-level content is higher), the cost of real estate construction (according to the building square meter) . pile engineering (if any): 70 ~ 100 yuan / . concrete: 0.3 ~ 0.5 cubic meters / square meters (low content of the multi-layer, high-level high), together 100 ~ 165 yuan / square meter; . masonry works: 60 . plastering works: 25 to 40 yuan / square meter; . external wall works (including insulation): 50 ~ 100 yuan / square meter (high temperature; (Including fire as the standard), such as stone or curtain wall, it may be as high as 300 ~ 1000 yuan / square meter; . indoor water and electricity installation works (including fire): 60 ~ 120 yuan / square meter (according to cell grade, . doors and windows project (not included in the door): per square meter of building area of ??the doors and windows area of ??about (the higher than the high-level, high-level low); . 0.25 ~ 0.5 square meters (with the design and whether the high-grade great relationship, the proportion of high-end large), the cost of 90 to 300 yuan / square meter, generally 90 to 150 yuan / square meters, such as . earth, into the door, flue and public parts of the decoration works: 30 to 150 yuan / square meter (10 yuan / square feet, flue and public parts decoration works: 30 ~ 150 yuan / square meter And the level of high and low level of the relationship between the higher grade, the higher the cost);

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

There are many reasons for the occurrence of sand, there is a problem of matching, construction and conservation of the problem, cement or sand itself, the problem, only according to the actual situation to find sand causes, and thus the right medicine, for protection.
