There are different types of reactive powder concrete (RPC) and researchers continue to develop better-quality mix designs. This research presents an integrated approach for RPC design. For this purpose, 13 designs were collected according expert opinion laboratory samples tested in study validation the characteristics compressive strength water absorption. The then ranked using simple additive...

This research is carried out to investigate the Gaussian process regression (GPR) based on a machine learning model predict compressive strength of Miscanthus lightweight concrete (MLWC). A database 414 experimental data, which includes nine input variables such as six mix constituents concrete, form specimen, curing time and pre-treatment condition an output variable MLWC, constructed from dat...

In this study, first by surveythe parameters affecting the compressive strength, such as water to cement ratio, cementgrade, silica fume to cement percentage, and the various ratios oflight weight aggregate LECA, to total aggregate, Taguchi method is used, to test 9 mix designsobtained the mix design optimization. Since lightweight concrete is brittle like normal concrete, to resolve this probl...

The design of cryptographic hash functions is a very complex and failure-prone process. For this reason, this paper puts forward a completely modular and fault-tolerant approach to the construction of a full-fledged hash function from an underlying simpler hash function H and a further primitive F (such as a block cipher), with the property that collision resistance of the construction only rel...
