Quarry Reject Stone Chips In Concretes Application

This topic has studied the quarry waste material stone chips application situation.The stone chips is the quarry produces in the machine-finishing crushed stone process, the mining stone material with makes the concretes coarse aggregate at the same time, often is following the stone chips (particle size is smaller than the 10mm pellet) the production. Statistics indicated that produces the 100m3 crushed stone every time, will produce 20-30 m3 stone chipses. The massive stone chipses not only take the land, will also bring the serious environmental pollution. Stone chips generation of granulated substance use, both may solve the contamination concern, and may avoid mining the river sand excessively to the environment destruction, the economic efficiency is also quite considerable.The stone chips is different with the home scrap industrial refuse, compares says in the home scrap, the stone chips has the widespread application value. The natural sand is the non-renewable resources, the coarse sand were already getting fewer and fewer. Some area's natural sand resources are not rich, Yangtze River has limited now along the route picks the granulated substance, causes the granulated substance shortage of resources the contradiction to be day by day prominent。The artificial granulated substance was also in the nationwide scale just started the stage, was more important to its quality's guarantee. Namely resources superiority: May use each kind to abandon the resources, simultaneously, displays the price or the cost difference major characteristic. Quality superiority: Manifests stably (produces source for the quality to be fixed, mechanized production); The grain composition is reasonable, is adjustable; The stone powder can use three major characteristics reasonably.This article the stone chips which produces in view of the Taiyuan quarry conducts the experimental study, through in the different allocated proportion, with the natural sand in the mechanical properties, the mix performance, the lasting quality, the pump over performance, the microscopic analysis, the economical performance and so on various comparison, summarizes the stone chips to apply in the concretes merit as well as the deficiency, the more careful comprehensive explanation stone chips has used in the concretes the feasibility, the usability as well as the high performance the reason.
