Leading into its Technology Forum #34 in Indianapolis, SDC will host “Establishing Standards of Care for Prepackaged Powdered Materials for Use in Construction,” a September 4 workshop on quality control impacting end uses of cement-based repair products and grouts. Among issues organizers will target: unwanted chlorides inadvertently added to the cement; contamination of product from previous use of blending equipment; large bag weight variations affecting binder to liquid ratios and cured properties; tested mechanical properties falling below specifications; and, segregation of product components after mixing and placement. Workshop presenters will aim to bring understanding of packaged-mix product variability and quality, plus impacts on the industry from subpar product. –
