Studyfrom the choice of materials, construction techniques and pouring conservationand other aspects of the special requirements of the silicon powder concreteconstruction. Engineering examples prove that the silicon powder concretehydraulic structures with superior performance than ordinary concrete.

Silicon powder is ferroalloy smelting generatedby high purity quartz and coke chemical reaction in electric arc furnace, andobtained by collecting emissions of gas powder in the electric arc furnace.1982 metalpowder supplier first time added silicon powder into concrete andcomprehensive study of its performance, silicon powder concrete cause people’s concerns.Due to the complementary properties of silicon powder concrete and Portlandcement, coupled with the benefit of environmental protection (silicon powderwith the electric arc furnace gas into the air, causing severe dust pollution),silicon powder has been identified as a new auxiliary cementing material beingwidely studied and applied.

Adding silicon powder can effectivelyreduce the accumulation of moisture in concrete and steel interface, to improvethe adhesion of reinforced concrete. Under the same conditions of the water-cementratio and concrete mix proportion, the compressive strength of mix siliconpowder concrete was significantly higher than ordinary concrete. Experimentalstudies have shown that more than 20% silicon powder dosage in concrete, the compressivestrength of silicon powder concrete no longer increase with increasing siliconpowder dosage; silicon powder dosage does not exceed 20%, the elastic modulusof the silicon powder concrete is increased with the silicon powder contentincreased.

Silicon powder average particle size is 100 mm, belong to the case of nano-particles, with superiorperformance of the concrete mixer truck cleaning volcanic ash. Added to cement concrete, not only can fillthe voids of the cement, more important is the nanometer silicon powder reactwith Ca (OH) 2 in thecement paste, generated colloidal hydrated calcium silicate, improve theinterface of cement paste and aggregates structure and performance. Reduceporosity, enhanced the concrete impermeability and durability. The study showedthat the silicon powder concrete can effectively resist the CL-penetration, andgreatly reduce the corrosion of reinforced concrete CL-invasive Shun tendonscracks, in order to effectively improve the performance of concrete cracking.This superiority is especially suitable for a harbor concrete engineering.

Due to the silicon powder special physicaland chemical properties, can be used in manufacturing high-strength, lowpermeability and chemical resistance of concrete, in hydraulic structures,transportation, building construction all have a huge market. But siliconpowder concrete construction technology and ordinary concrete is not the same,only to strictly observe and correct use of silicon powder concrete productswill get qualified.

Silicon powder in the transport and storagemust be kept dry and not damp. For ease of use, silicon powder can mechanicalagitation into a uniform slurry concentration of 30% to reserve seven daysbefore use. The stored slurry pond must be clean and watertight, covered toavoid evaporation and to prevent the inflow of rain and sewage. Beforeconstruction, to prevent sediment stratification must be stirring frequently toensure uniformity. Silicon powder concrete slump is sensitive to the amount ofwater added. The moisture content should be measured before construction,aggregate construction site and calculate concrete design water, additives toprevent agglomeration, best made solution Stirbefore using. Silicon powder concrete as a surface layer with ordinary concretepouring, before the initial setting ordinary concrete vibrators laid siliconpowder concrete, and used pokers inserted ordinary concrete layer 2 cm vibration compacting, guaranteebetter concrete bonding between layers.

In addition to reducing household waste, a food waste disposer can reduce the amount of waste that goes as land-fill. Waste has become a major global issue and legally binding limits have been established for some countries on the amount of food waste that can be used as land-fill. A food waste disposer can reduce the volume of waste going as land-fill dramatically, by up to 50%. Life-cycle studies have identified major cost benefits from using the food waste disposer rather than land-fill methods alone. Ground food waste channeled to a waste water treatment plant can create valuable fertilizer and generate energy by capturing methane gas. Food waste disposers complement the compost pile. Composting is an environmentally-friendly way to use the space in yards to slowly break-down organic matter such as food waste. Composting with food waste is not an option for many people who have neither the necessary space nor the time to tend to a compost pile. Additionally, protein food waste such concrete mixer truck cleaning Suppliers as meat, fish, dairy products and many cooked foods should not be put on a compost pile. The decay process is different from that of green waste and can produce harmful pathogens, noxious smells and be an obvious attractant for rodents and insects.

Construction Waste Recycling,Construction Waste Plant

Construction waste recycling and demolition materials produced at a construction location are increasingly significant. The environmental advantage of recycling can be considerable. A great deal of this energy savings result from reduced utilization of natural wealth, such as mining crushed aggregates or extraction, and the refining of petroleum. In addition to saving energy, recycling keeps the materials away from landfills. In addition to the environmental advantage, recycling will also have monetary benefit.

Construction waste  or using materials on site can decrease material transportation and removal expenses. The materials can be separated on site by being placed in boxes or piles. It is essential to keep the materials as uncontaminated as possible by keeping other waste out of the recycling piles. Waste concrete can be ground for use as fill, and neat wood, drywall, and cardboard can be used at the site for soil improvement. Small portable grinders can be comparatively intelligent high pressure plunger pump economical and secure to use at sites. Such equipment can be fastened to pickup trucks. Recycling that needs reprocessing is not generally feasible economically, unless a facility for using recycled materials is situated close to the source.

Recycling of materials can save significant money for the state and other purchasers, generate additional trade prospects, save energy by performing recycling at site, and preserve thinning resources. According to the studies carried out, recycling is performed at a small scale that needs to be enhanced to obtain the advantages of wet milling process. For example, the recycling of asphalt is essential because the roads are being increasingly deteriorated due to the manifold increase in traffic load and volume, reduced funding, and the increased requirement for an efficient transportation system. To reiterate the cost reduction, a paving project of a 4-inch overlay by using conventional materials was estimated at $55,000. The same task could be completed at $32,000 through the use of recycled materials, resulting in a savings of $13,000. Similarly, there are substantial savings in other fields from the use of recycled materials.
