Embodiment 1

[0030] Embodiment 1 A kind of preparation method of slope protection block

[0031] The preparation method comprises the following steps:

[0032] 1) The selection of gravel should consider its toughness and strength, the content of harmful impurities, particle gradation, particle shape and surface characteristics. In this embodiment, crushed stones from a better quarry are selected, and the maximum particle size is controlled within 40mm, which meets the requirements. Natural sand requires the fine aggregate to be hard in geology, low in harmful substances, and clean. In this embodiment, medium sand is selected to meet the requirements. The steel slag selected in this embodiment is the steel slag produced by Jinan Iron and Steel Co., Ltd., which is massive steel slag, black in color, heavier than pebbles, rough in surface, more pores, below 20mm in particle size, and continuous gradation of 5-20mm. fulfil requirements. Firstly, the sieves are listed from top to bottom in t...

Abstract

The invention relates to the technical field of dike slope protection engineering, in particular to concrete for slope protection blocks and a method for preparing the slope protection blocks. The concrete for the slope protection blocks is made from steel slag, fly ash, cement, water, a water reducing agent, gravels and sand according to a ratio, wherein the steel slag is divided into three partsof steel slag stone, steel slag sand and steel slag powder through sieves. The mechanical properties of the slope protection blocks made from the concrete are improved significantly, especially the compression resistance and fracture resistance, and when the blocks made from the concrete are compared with ordinary concrete blocks, the durability is improved, and resistance to carbonizing and resistance to water penetration are improved remarkably.

Description

technical field [0001] The invention relates to the technical field of embankment slope protection engineering, in particular to a method for preparing concrete used for slope protection blocks and slope protection blocks. Background technique [0002] The stability of the dam bank directly affects the stability requirements of river channel flooding, and the traditional stone slope protection form is uneconomical and seriously damages the ecological environment. Since stone is a non-renewable resource, the cost of using stone as a slope protection material is high, and it will also cause waste of resources. Stone resources are increasingly scarce. It is imminent to study new materials for the reinforcement of dangerous engineering dam slopes. For this reason, in recent years, people have begun to develop different types of concrete blocks to replace natural stones. However, these products have disadvantages such as complex production processes, high costs, and difficulty in...
