what are the challenges facing the new energy microsilica industry-pg电玩城

industry experts believe that china's energy internet construction will drive gdp growth by more than 1.5 percentage points annually in the next 10 years, and will strongly drive the development of a number of strategic emerging industries such as new energy, new materials, intelligent manufacturing and electric vehicles.

it is worth noting that as an important part of the energy internet, new energy development faces challenges under the pressure of capacity reduction. under the situation of capacity reduction and slow growth of energy consumption, how to solve the problem of new energy integration and absorption is still the bottleneck problem that restricts the sustainable and rapid development of new energy. energy expert wang jin said that solving problems such as smog requires fast development of new energy, but there are still many obstacles in the process of replacing traditional energy sources with new energy. first, the cost of new energy is relatively high, and subsidies are needed for both wind power and photovoltaic. second, after the development of new energy, there are still many phenomena of water abandoning, light abandoning and wind abandoning.

the microsilica in the transition zone of cement slurry and aggregate interface reduces the bleeding of hpc, prevents moisture accumulation under the aggregate, makes the transition zone of aggregate interface similar to the microstructure of cement paste, thus improving the density of interfacial filter area and effectively reducing the thickness of interfacial transition zone. the tiny silicon particles become the "seed" of ca(oh)2, making the crystal size of ca(oh)2 smaller and more random orientation.

a few caveats:

1. bauxite aggregate and fine powder must be sintered, and it is best to use the same batch for each experiment.

2. aluminum cement is best used for each experiment with newly opened packaging and stable quality cement.

3. liquidity varies in different seasons.

the engineering practice shows that controlling the cracks of the micro-sillite concrete by all means is the key to the construction of micro-sillite concrete. therefore, the curing of microsilica concrete is ahead of ordinary concrete. concrete pouring is completed before the final set, must immediately spray method is used to reduce moisture to evaporate or the use of plastic mulch or spraying concrete curing agent curing, keep the concrete surface wet, but unfavorable droplets of water flow and visible: concrete after the final set, should continue to curing agent or covering plastic film or spraying on the surface covering wet straw bag and sprinkler maintenance, keep the concrete in the wet state, curing time should be no less than 28 d. lin bao-yu and wu shao-zhang of nanjing institute of water resources have studied measures to reduce the plastic cracking and early drying shrinkage of silicone-powder concrete.
