施工现场的气温高于30℃，拌和物摊铺温度在30~35℃，同时，空气相对

When the temperature is higher than the construction site 30 ℃, paving mixes temperature 30 ~ 35 ℃, while less than 80% relative humidity, high temperature season should construction concrete pavement construction provisions. <br>When the temperature is greater than or equal field 30 ℃, construction period should avoid the midday heat, optionally in the morning, evening or night construction, the construction should have good night operation of the lighting and to ensure the safety of construction. <br>Mixing was to be mixed with a sufficient dose of retarder, high temperature retarder, or retarding PLASTICIZER (high) water reducer. <br>Concrete mixture should be added to cover the dump truck. <br>Should speed up the convergence of all aspects of construction, try to stir compression, transportation, paving, decorative and other aspects of the process time-consuming. <br>May be used as anti-sun awning canopy. Daily maximum temperature in the shade and the most intense periods of sunshine. <br>When mulching moisturizing regimen, watering should be strengthened, and maintain sufficient humidity. <br>Slit should be considered concrete strength or growth temperature by the hour meter 250, an appropriate construction cheaper than normal early slit, to prevent broken board. Especially at night when the cooling rate greater or rain, should be ahead of the slit.

The temperature at the construction site is higher than 30 degrees C, the temperature of mixing and paving is 30 to 35 degrees C, at the same time, when the relative humidity of air is less than 80%, the construction of concrete pavement should be carried out according to the provisions of the construction of the high temperature season.<br>When the on-site temperature is greater than or equal to 30 degrees C, should avoid the noon high temperature period construction, can choose in the morning, evening or night construction, night construction should have good operating lighting, and ensure construction safety.<br>The mixture should be mixed with sufficient doses of retardants, high temperature retardants, plasticizers or slow coagulation (efficient) water reduction agents, etc.<br>The concrete mix on the dump truck should be covered.<br>We should speed up the convergence of all aspects of construction, as far as possible to compress the stirring, transportation, paving, finishes and other process links spent time.<br>A hood can be used as a sun shield. Shade during periods when the temperature is highest and the sun shines most strongly.<br>When using cover ediconditioning, you should strengthen sprinklers and maintain adequate humidity.<br>The cut should be depending on the increase of concrete strength or according to 250 temperature hours, it is appropriate to cut the seam sewell secate sethes appropriately earlier than the normal temperature construction to prevent the cutting of the plate. In particular, when the cooling range is large at night or rainfall, the seams should be cut early.

When the temperature of the construction site is higher than 30 ℃, the paving temperature of the mixture is 30-35 ℃, and the relative humidity of the air is less than 80%, the construction of the concrete pavement shall be carried out according to the provisions of the construction in the high temperature season.<br>When the site temperature is more than or equal to 30 ℃, construction shall be avoided in the high temperature period at noon, and construction can be carried out in the morning, evening or night. Good operation lighting shall be provided for night construction to ensure construction safety.<br>The mixture shall be mixed with sufficient dosage of retarder, high-temperature retarder, plasticizer or retarded (high-efficiency) water reducer, etc.<br>The concrete mixture on the dump truck shall be covered.<br>The connection of all construction links shall be accelerated, and the time spent in mixing, transportation, paving, facing and other process links shall be compressed as much as possible.<br>Rain proof awning can be used as sun proof awning. Shade in the period with the highest daily temperature and the strongest sunshine.<br>When using covering for moisture preservation, it is necessary to strengthen watering and maintain sufficient humidity.<br>According to the growth of concrete strength or 250 hours of temperature, the joint shall be cut earlier than the normal temperature construction to prevent the slab from breaking. Especially in the case of large temperature drop or rainfall at night, the joint should be cut early.
