Product Description

heavy encrypted silica fume for teahouse cement:This Microsilica is generally added to the cement used in the construction of teahouses.

(1) The builder should formulate the construction technology programme for large volume concrete to take temperature control measures, and set up a special person to carry out moisturising and thermal insulation and maintenance work, and reasonably set up temperature measurement holes to measure the temperature of the concrete. During the maintenance period according to the temperature measurement of the concrete to maintain and expand the measures to be adjusted in a timely manner.

(2) Concrete should be poured before the insulation measures, ready to plastic film, quilt or felt and other moisturising and heat preservation materials.
(3) after pouring to the elevation of the concrete, the concrete ten for plastering, should then cover the surface of the plastic film, and in the pear film covered with felt and other heat preservation materials, on the edge, corner parts of the thickness of the heat preservation materials should be increased to the surface parts of the 2 ~ 3 times. After covering the thermal insulation material, no more wine conservation, in order to prevent the occurrence of temperature cracks on the surface of the concrete.
(4) The duration of moisturising curing shall not be less than 14d, and during the concrete curing period, it is necessary to prevent sudden changes in temperature and prevent wind and water loss. The thickness of the insulation material should be increased at night to prevent the temperature difference between inside and outside from increasing.

(5) The removal of thermal insulation covering materials should be gradual in layers, when the maximum temperature difference between the surface temperature of the concrete and the ambient temperature is less than 20 ℃, it can be completely removed.
