The cement pipeline project is closely related to the people's production and life. The use of the cement pipeline project involves the vital interests of millions of households, and it is related to the ecological problems of urban flood prevention and groundwater and soil pollution. So it is of great significance. Next, we will introduce the usefulness of raw materials for cement drainage pipes.
The cement pipeline project is a concealed project. Only by strengthening the control of various links in the construction process can we prevent the occurrence of various common diseases and ensure that the overall project construction is excellent.
The use of raw materials for cement drainage pipes: water is required to meet the hydration requirements of cement. The common water-cement ratio of ordinary concrete is 0.40 ~ 0.65. Water that exceeds the hydration requirements is mainly to meet the workability requirements. Excessive amount of water leaves holes in the concrete, which adversely affects the strength, density, and various durability of the concrete, such as cement pipes, which cause water leakage due to excessive water addition. Seriously affect quality.
The effect of cement on the function of concrete lies primarily in the type and quantity of mineral components and the fineness of the cement. Tricalcium silicate in cement is the primary deposit of cement clinker, with a content of about 50%, and is the primary source of cement gelability. Tricalcium silicate reacts with water and is called hydration, producing hydrated calcium silicate, which is gel-like. The hydrated calcium silicate gel has a cementing effect on the sand and gravel aggregate in the concrete, fills the pores therebetween, and hardens into an artificial stone.
Gravel is called aggregate, also known as aggregate, which accounts for about 70% to 80% of the volume in concrete. For a long time in the past, aggregates were regarded as inert materials, and it was believed that only the effect of forming a volume in concrete was considered, and the function of concrete was not greatly affected.
