In the conditions of hot and dry climate, concrete mixture quickly loses its mobility workability. this regard, it is necessary to plasticize by introducing various surfactants; at same time, surfactant additive should not slow down process hydration hardening. To ensure salt resistance, increase density strength concrete. The proposed complex obtained joint grinding in a ball mill soda sulfate...

In this study, Self-Compacting Concrete (SSC) was produced by using Fly Ash (FA) and Marble Powder (MP), which reduces the amount of cement, causes less damage to environment has some superior properties compared normal concrete. The changes in physical mechanical SSCs with increasing age were investigated. CEM I 42.5 R cement used as a binder production SSC. It FA MP at rates 10%, 20% 30% weig...

This study proposed the use of polyaniline–alkaline copper carbonate composites as anti-corrosion and anti-biofouling concrete additives established a set high-dispersion preparation methods for this composite additive. The effects in were investigated marine environments via specimens, actual sea suspension experiments, mechanical property tests, biological attachment avoidance tests. experime...

Contour Crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The Contour Crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for Contour Crafting benefit the technology by increasin...
