The detailed information :
The use of water in cement tube machine the benefits of increased aid
The use of water in cement tube machine the benefits of increased aid
Used in cement tube machine water increased aid can trigger the early strength of cement, Portland cement grinding aid in salt and alkali. But not to the late strength of cement to assist, even after 28 days strength decline or increase rate is low, so that influence the engineering quality. Containing alkali admixture in cement and the environment provides the alkali content of more, alkali active component is contained in aggregate, necessary conditions of alkali aggregate reaction. Concrete under the effect of the environment and the medium temporary, strength, shape and internal structure will have some change, but not the crack, deformation and damage, it is considered with the durability of concrete. Concrete grinding agent except for have a certain strength of peace to accept load, also should have the durability, such as impermeability, frost resistance, abrasion resistance, heat resistance, weathering resistance, etc. Concrete durability is a comprehensive technical indicators, according to the using conditions and environment to make analysis and find the solution, ensure the quality of construction project an important part of the expedient. Promoted the beta C2S amorphization. C3S content in clinker grinding grinding agent after 10 hours, add a grinding agent (triethanolamine) cases. Compared with not adding the clinker grinding agent, grain size and lattice deformation respectively by 77.9 nm 0.440 47.6 nm 0.2939 this shows grinding agent to improve the particle can easy to grind and deformation plays an important role.
