High temperature, hot summer and rainy season have brought many adverse effects to the concrete production of Tongya Company. Facing the adverse environmental factors, Tongya Company has taken countermeasures to strictly control the technology, quality and production to ensure the normal construction of each construction site in summer and guarantee the supply of concrete.

First of all, do a good job of raw materials processing, to prepare for high temperature production.They cool the raw material and resist the high summer temperatures.The sand, stone, cement and other raw materials needed for concrete production should be cooled and cooled before mixing to make concrete, so as to improve the adverse factors brought by hot weather.The sand stone storage room, and spray water to reduce the temperature;The cement is stored in separate silos, and the double silos are used in reverse to ensure adequate cooling of cement.Closed storage of additives, sun shading and sun protection.In order to cope with the rainy weather, they strengthen the sampling frequency of sand and stone, cement and other raw materials strictly tested, to prevent too large moisture content affect the performance and strength of concrete finished products.

Secondly, the mix ratio design is optimized to improve the quality of concrete.Through experiments, they find the optimal water consumption, select appropriate admixtures, determine the reasonable amount of admixtures, control the hydration rate, and then control the release of temperature to resist the environmental impact of high temperature weather;The strength of concrete after setting and hardening is guaranteed by optimizing the proportion of aggregate, cement and water.According to different weather conditions and engineering needs, the laboratory adjusts the mix ratio in time to ensure that on the basis of ensuring the concrete strength, the influence of evaporation or moisture on the concrete is prevented and the concrete workability index is met.Technicians strictly in accordance with the national standards, combined with their own technical advantages, accurate measurement of concrete ingredients, the production of high temperature and high humidity of summer concrete products, to meet the requirements of the construction enterprises in summer construction.

Third, technical personnel on-site supervision of production, to prevent problems in the production process.Technicians strictly control the construction standard of slump of mixed concrete on site, so as to avoid the high temperature in summer and the rapid evaporation of water affecting the quality of concrete.Strict site management, prohibit the process of water allocation, if need to adjust must use quality inspection qualified admixture adjustment.In the process of mixing, strict inspection and control ensure the quality of concrete production.

Four is to do a good job in the detection of concrete finished products, good quality of finished products.They strictly implement the requirements of testing experiments, do every 100 plates to do a group of test samples, strict quality testing in the laboratory, to ensure that the products meet the national technical standards and engineering quality requirements, prohibited unqualified products into the market.

Five is to do concrete pouring site technical guidance, ensure concrete is used correctly.In view of the adverse weather factors such as high temperature and rainy weather in summer, according to the specific conditions of construction, they arrange technicians to go deep into the construction site to guide pouring, and conscientiously implement the technical requirements from pouring to vibrating to ensure that the concrete is dense and has no cracks, so as to meet the requirements of building strength and use.In the process of pouring, the concrete pouring rate should be carefully controlled to control the degree of hardening and heat release, so as to adapt to the high temperature construction environment. At the same time, the construction unit should be required to carry out concrete spray, water sprinkling and film curing in time to prevent the uneven expansion cracks caused by the temperature difference between inside and outside.

Six is to do a good job at wrong time supply according to the requirements of the construction party.They follow the characteristics of summer construction, combined with the construction time of the construction side, flexible arrangement of concrete production and supply, not only to avoid the concrete in the way of solidification caused by waste, but also to ensure that the concrete will be used.

Seven it is to ensure concrete safety transport.In order to prevent the driver from heat stroke caused by the high temperature in summer, the evaporation of concrete moisture is serious, and to ensure the safety of product quality and personnel during transportation, they organize and coordinate the commercial concrete truck driver to transport according to plan, so that the driver can have a good rest in high temperature, and concentrate on transporting concrete when cool, ensuring the quality of concrete while ensuring the safety of people and vehicles.

From the production source to the construction site, the company strictly controls the quality, implements supervision throughout the whole process, takes multiple measures to deal with the summer construction, and strictly implements technical standards, so as to ensure the normal supply of concrete in summer and meet the needs of various construction sites.
