Concrete Analysis and Engineering Investigations
Geochempet is the leading company when it comes to harden concrete analysis as well as engineering investigations. Over the last 20 years we have lead many in depth investigation in product failures and preventive research for leading construction and supply companies. With specialist knowledge and experience in deleterious alkaline silica reactivity and other common causes for deteriorating harden concrete structures such as bridges and roads as well as experience in tiles and other concrete based building products.
The petrographic report into harden concrete takes account of ASTM C 856 Standard Recommended Practice for Petrographic Examination of Hardened Concrete and involves visual examination of the core or other samples submitted and preparation of one or more thin section for microscopic examination. Information is provided on the nature and proportions of coarse and fine aggregates, cement, voids, carbonation depth, fractures, AAR reaction products, and comments on requested aspects. SEM analysis maybe used to confirm presence of very fine deleterious components if required.
