Safety, fairness and the new era of workplace drug testing

The ready-mix concrete industry prides itself on leveraging technology to optimize the customer experience. Its technology investments generally focus on improving production and delivery such as quality and service. To its discredit, technology does not always provide direct benefits to employees—the resource that leaders in ready-mix production universally acknowledge is the most important. However, through the championing of cutting-edge technology,…

Concrete Maturity Method: Tradition Enables Innovation

The construction materials testing (CMT) industry is excited by the possibilities of estimating concrete strength via the non-destructive maturity method. This method provides a number of enhancements to the traditional laboratory compression test method. But the maturity method is not an alternative or replacement. Indeed, maturity testing relies completely on the traditional compression test method.

Fast returns flow from silo aeration retrofit investment

Flooring materials manufacturer Forpac realized more efficient operation through an investment in modern silo aeration at its Haines City, Fla. operation. “We had been operating with airpads in our 144-ton silos that store white cement powder and calcium carbonate used to make our thin set adhesive and grout for tile floors,” observes Plant Manager Mike Dulin. The result, he adds,…

Mix and Washout Recycling Equipment

Concrete plant/yard space limitations, tightening storm and process water management rules, escalating waste-concrete hauling and disposal costs, and sustainability-driven water recycling measures are prompting more producers to invest in mix reclaiming and slurry filter press equipment. Concrete Products visits key players in both categories.

Complete Load Solutions finishes critical electronic communications link

Losses from operational miscues, a general lack of ready mixed concrete dispatch and batch process efficiency, and significant task redundancies triggered a software programming and Internet of Things technology project leading to the late-2019 launch of Complete Load Solutions, LLC. By fully realizing communications links between dispatch software, batch software, and mixer trucks, the Chicago-based firm aims to eliminate load-out errors, while maximizing plant production.
