Chinese quarry producer Beijing Xindadi Equipment Company is looking to increase the size of its Caterpillar machine fleet as part of its plan to increase output.

The company is based at Beijing Miyun Taishi Village and currently produces 1-1.5 million tonnes/year of limestone, which is used for general construction in the Beijing area, writes Mike Woof.

Zhang Guofeng is equipment manager for the firm and said, “Business is good because the market is not affected by the downturn.”

The formula for making concrete: water, cement and aggregates, seems simple, but concrete manufacture is a complex process. Developing various mixes for concrete requires advanced scientific skills, with the quality of the cement and aggregates and the dosage and proportions just some of the variables that influence the properties of concrete.

Likewise, the equipment for producing concrete has become more sophisticated over the years with precision measurement of the ingredients now standard on most mac
