Select mixing plant site need to pay attention to what points?1.Construction of mixing plant should choose a flat, wide, away from residential areas。If the hillside terrain can be fully utilized and the material field is set on the higher ground plane of the hillside, the loading height of the batching machine can be reduced, so that the climbing Angle on the loader is small or no climbing.tangibleConcrete mixing plantproducerIt saves energy and reduces wear。2 Convenient transportation (for tank trucks, pump trucks, cement trucks, etc.) 3.It should be built next to the material yard. The distance between the material yard and the sand plant should be close to ensure that the water supply is sufficient。According to the existing natural landform of the mixing station site, the production area and living area of the mixing station can be divided into two independent areas, the size of the available site in the living area is 36M×70M, and the production area of the mixing station is a rectangle.tangibleConcrete mixing plantproducerThe site is basically flat and in place。But to consider the ground drainage, so that there is no water phenomenon。
(1) The selection of admixtures There are many admixtures with different effects, especially for different types of cement。tangibleConcrete mixing plantproducerIn the selection of admixtures, should be based on the needs of the project, the site of the material conditions, with reference to the relevant information, through the test to determine。(2) Determination of admixtures The admixtures of concrete have appropriate admixtures, and the admixtures are too small, often unable to achieve the expected effect;If the amount is too large, it will cause waste, sometimes affect the quality of concrete, and even cause quality accidents。Therefore, the optimal dosage should be determined by test。(3) Adding methods of admixtures Different methods of adding admixtures into concrete mixes, the effect is different。For example, the effect of post-blending method is better than that of pre-blending method and co-blending method, and its dosage is only half of that of pre-blending method and co-blending method。The so-called first blending method is to mix the water-reducing agent with cement first and then mix with aggregate and water;The co-blending method is to dissolve the water-reducing agent in water to form a solution and then add it to the mixture to stir together.Post-mixing method means that after the concrete mix is sent to the pouring site, water reducing agent is added and then evenly mixed again for pouring。 因此,Concrete mixing plantproducerThe use of admixtures should be determined by tests according to engineering characteristics, material conditions and construction conditions。
