Developing a More Rapid Test to Assess Sulfate Resistance of Hydraulic Cements
External sulfate attack of concrete is a major problem that can appear in regions where concrete is exposed to soil or water containing sulfates, leading to softening and cracking of the concrete. Therefore, it is important that materials selection and proportioning of concrete in susceptible regions be carefully considered to resist sulfate attack. American Society for Testing Materials (ASTM)...
متن کاملComparison of Compressive Strength of Five Hydraulic Cements
Objectives: Maintaining pulp vitality is a main goal in restorative dentistry. Introduction of pulp capping agents paved the way to eliminate the shortcomings of these materials and obtain successful restorations. On the other hand, nanotechnology is an emerging field of science with increasing use in dental materials. This study sought to assess the effect of addition of nano-TiO2, nano-SiO...

متن کاملResearch Article: A rapid approach to assess estrogenic transcriptional activity of bisphenol A in the liver of goldfish
Bisphenol A (BPA) is a synthetic compound widely used in types of consumer goods and medical tools. It has been shown that BPA acts as an endocrine disruptor chemical casuing negative impact on reproductive functions. The present study used an in vitro approach to assess estrogenic transcriptional activity of BPA as a rapid and sensitive method. The cultured pieces of hepatic tissue of goldfish...
متن کاملDevelopment of an Astm Standard Test Method on X-ray Powder Diffraction Analysis of Hydraulic Cements
X-ray powder diffraction provides a direct analysis of phase abundance of portland cement clinkers and cements. The ASTM C01 (Cement) Committee formed a task group to investigate quantitative X-ray powder diffraction analysis that resulted in the ASTM C 1365 standard test for X-ray powder diffraction of portland cement clinker and portland cement. Estimates of test precision and bias are requir...
