Concrete with gangue which made with ordinary Portland cement at different water binder ratio (0.35, 0.40 and 0.45) or ordinary Portland cement at water binder ratio of 0.35 incorporating 10% fly ash or 20% fly ash; 20% fly ash and 1% early strength agent, slag with the replacement of 15% or 30%, or 15% fly ash and 15% slag were made and exposed to a wetting–drying sulfate environment. The comp...

Stabilized dredged sediments are used as a backfilling material to reduce construction costs and solution environmental protection. Therefore, the compressive strength is an important criterion determine stabilized application such road construction, building highway construction. Using traditional method empirical approach experimental methods, determination of difficult due complexity this co...

Superplasticizers (SPs), also known as naturally high-water reducers, are substances used to create high-strength concrete. Due the system’s complexity, predicting concrete’s compressive strength can be difficult. In this study, a prediction model for with SP was developed handle high-dimensional complex non-linear relationship between mixing design of and After performing statistical analysis ...

Concrete is the most used building material in world, due to its high compressive strength and durability. Those properties are measured assessed fresh hardened states of concrete, with standard methods which time cost consuming. In present study, slump concrete has been predicted using Artificial Neural Network (ANN), constructed different input parameters involving mix design (i.e. coarse &am...

Silica fume has been largely used in concrete in recent decades due to its effect on improvement of strength and &#10durability of concrete. On the other hand, attention has been recently paid to the use of limestone powder as a substitute for part of cement in concrete, basically because of its low price and its positive effect on the durability of concrete. The aim of the current study is the...
