Effect of heavy metal and magnesium sulfate on properties of high strength cement mortar

  The effect of lead (Pb) present in mixing water on compressive strength, setting times, soundness and magnesium sulfate attack on high strength cement mortar was experimentally evaluated. Cement mortar specimens were cast using deionised water and lead (Pb) spiked deionized water for reference and the test specimens as mixing waters respectively. On comparison with reference specimens, at higher...

Reflectance spectroscopy as a tool to assess the quality of concrete in situ

  Modern high-performance concrete (HPC) is one of the most versatile, durable, and cost effective building materials known to man. Its composition has been well-characterized in 'test sample' reports from laboratory specimens and trial castings: however, its internal structure often reveals large differences from that of 'test sample concrete'. Moreover, the test procedure is considered...
