High-strength concrete, pipeline prepared by high-strength concrete and method for preparing pipeline

Abstract

The invention relates to high-strength concrete, a pipeline prepared by the high-strength concrete and a method for preparing the pipeline, and belongs to the field of concrete. The technical problem solved by the invention is to provide the concrete with high compressive strength. The high-strength concrete is prepared from the following raw materials in part by weight: 0.8 to 1.2 parts of cement, 1.0 to 1.2 parts of mixed sand, 2.9 to 3.4 parts of gravel with a crushing value of between 9.0 and 10.0 percent, 0.25 to 0.4 part of water, and a water reducing agent which accounts for 0.7 to 0.9percent of the total weight of the raw materials of the concrete, wherein the mixed sand is formed by mixing 40 to 60 percent of river sand and 60 to 40 percent of artificial sand. The high-strength concrete does not need to add the raw materials such as mineral powder, ground sand and the like additionally, which not only simplifies working procedures, but also reduces production cost; and the high-strength concrete has high compressive strength and good anti-permeability performance, can be used for the preparation of deep-buried concrete pipelines, provide a new selection for the field, and has broad application prospect.

Description

technical field [0001] The invention relates to a high-strength concrete, a pipeline prepared by using it and a method for preparing the pipeline, belonging to the field of concrete. Background technique [0002] As a building material, concrete has the advantages of simple construction, high strength, good stability, good durability, and low maintenance cost. Therefore, concrete is commonly used to prepare sewage pipes, etc. The general sewage pipeline is buried about 1 to 2 meters below the ground surface, and the strength of the concrete is not high. But if the pipeline crosses the river, in order to prevent the sewage in the sewage pipeline from infiltrating and polluting the river water, the sewage pipeline needs to be buried more than tens of meters deep at the bottom of the river, which increases the strength and anti-permeability of the concrete used to prepare the sewage pipeline. Requirements such as . [0003] The patent application with the application number 2...
