Energy consumption to produce one cubic meter of reinforced concrete in individual enterprises is twice the scientifically-based standard. Analysis of the energy in precast concrete industry can identify the most energy-intensive processes and redistribution of individual, rational consumption of energy which can be most effective. In 1998. the production of a cube. meters of concrete on average spent 53.1 kg. at.
t. The heating of a cube. meters of concrete in the product along with the metallic form is required to spend up to 30% is actually spent by the heat, more than 20% of the energy for heat supply is inevitably lost in the failed state existing equipment. The main reduction of heat consumption is possible in the organization of cost accounting for all types of products, sovevrshenstvovanii existing thermal units, auto-tizatsii heat treatment, additional insulation thermal units, the transition to low-temperature heat treatment of products, economical distribution hodovanii energy for domestic needs of factories, etc. Over 90% of its factories of prefabricated concrete products subject to steaming, although the traditional method of heating and does not apply to most economical. During loading and unloading lost a lot of heat, the cooling chamber, Vaeth and on its heating with Each tab has to spend over heat. Analysis of pit steaming chambers in many plants of precast concrete shows that the majority of them are not tight water seal, twisted cover the gap between elements of the shutter and the chamber wall. All this leads to permanent and severe losses of thermal energy.
