High Strength, High Density Concrete
ACI Journal Proceedings, 1965 Abstract : Although high-density concrete found limited use as a shielding material against X-rays before the large-scale development of nuclear reactors and similar devices, the latter have been almost entirely responsible for the research and development that have been done on the production and use of high-density concrete as a shielding material ...

A Study on High Performance Fine-Grained Concrete Containing Rice Husk Ash [PDF]
, 2017 Rice husk ash (RHA) is classified as a highly reactive pozzolan. It has a very high silica content similar to that of silica fume (SF). Using less-expensive and locally available RHA as a mineral admixture in concrete brings ample benefits to the costs ...

Utility of pH-sensitive superabsorbent polymers in concrete repair [PDF]
, 2014 The largest issue with concrete is that cracks can occur due to its relatively low tensile strength. These cracks can generate an entrance for harmful compounds which are dissolved in fluids and gases and endanger the durability of concrete. The cost for
