Effects of Different Water and Super Plasticizer Amount, Pre-Setting and Curing Regimes on the Behavior of Reactive Powder Concrete
Reactive Powder Concrete (RPC) is an ultra high performance concrete which has superior mechanical and physical properties. The RPC is composed of cement and very fine powders such as crushed quartz (100–600 μm) and silica fume with very low water/binder ratio (W/B) (less than 0.20) and Super Plasticizer (SP). The RPC has a very high compressive and tensile strength with better durability prope...
متن کاملInfluence of Ultrafine 2CaO·SiO2 Powder on Hydration Properties of Reactive Powder Concrete
In this research, we assessed the influence of an ultrafine 2CaO·SiO₂ powder on the hydration properties of a reactive powder concrete system. The ultrafine powder was manufactured through chemical combustion method. The morphology of ultrafine powder and the development of hydration products in the cement paste prepared with ultrafine powder were investigated by scanning electron microscopy (S...
متن کاملEarly-Age Strength of Ultra-High Performance Concrete in Various Curing Conditions
The strength of Ultra-High Performance Concrete (UHPC) can be sensitively affected by the curing method used. However, in contrast to the precast plant production of UHPC where a standard high-temperature steam curing is available, an optimum curing condition is rarely realized with cast-in-place UHPC. Therefore, the trend of the compressive strength development of UHPC was experimentally inves...

متن کاملCuring efficiency of various resin-based materials polymerized through different ceramic thicknesses and curing time
PURPOSE The aim of this in vitro study was to examine the curing efficiency of various resin-based materials polymerized through ceramic restorations with 3 different thicknesses. Curing efficiency was evaluated by determining the surface microhardness (VHN) of the resin specimens. MATERIALS AND METHODS Four kinds of resin materials were used. Z350 (3M ESPE Filtek™ Z350: A2 Shade), Z250 (3M E...
