Description

technical field [0001] The invention relates to the technical field of cement maintenance equipment, in particular to a solar steam cement maintenance device. Background technique [0002] The reason why concrete can gradually harden after pouring and tamping is mainly due to the result of cement hydration, and hydration requires appropriate temperature and humidity conditions. Concrete must be cured. [0003] After the concrete is poured, if the climate is hot and the air is dry, without timely maintenance, the moisture in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will make the cement particles that have formed colloids unable to fully hydrate and cannot be transformed into stable crystals. The cohesive force of the concrete will cause flakes or powders to fall off on the concrete surface. In addition, when the concrete does not have sufficient strength, the premature evaporation of water will also cause large shrinkage deformation a...

Problems solved by technology

[0004] Steam cement curing is a commonly used means of cement curing now. Steam cement curing can increase the reaction temperature of concrete. In the initial stage of heating and heating, it mainly relies on the condensation and heat release of steam on concrete to transfer steam heat to concrete. The current cement Steam curing devices generally use steam generators, using conventional energy sources, which have problems such as high equipment prices, high energy consumption, inconvenient use in the field, not environmentally friendly, prone to failure, and large maintenance
