Concrete cost raw material prices

In recent years, constantly sand concrete machinery equipment, dry mortar equipment, continuous gradation mixing and other emerging products to market. China each year , nearly 3 billion cubic meters of concrete for infrastructure and major construction projects , it is estimated that the concrete industry is now at an annual rate of nearly 10 billion tons consumed gravel , sand for many years on the wanton exploitation of natural river sand brought growing scarcity of resources ,Concrete block machine raw material prices continued to rise concrete problems . To market mechanisms sand equipment can take advantage of construction wastes and other raw materials to produce alternative mechanisms sand sand, sand and gravel as to enhance the quality , protection of river sand resources to deal with construction waste and concrete block making machine solutions . Experts predict that the market mechanism will gradually increase the proportion of sand . Next decade efficient, environmentally friendly new sand equipment reached nearly billion annual market demand .
