SLUMP FLOW TEST ON SELF COMPACTING CONCRETE

Slump flow test and T50cm test on Self Compacting Concrete The slump flow test is used assess the horizontal free flow of in the absence of obstructions. It was first developed in Japan for use in assessment of underwater concrete. The ...

ROLLER COMPACTED CONCRETE

ROLLER COMPACTED CONCRETE IN PAVEMENT AND DAMS Roller-compacted concrete (RCC) is a concrete of zero-slump consistency in its unhardened state. It is transported, placed, and compacted using earth and rockfill construction equipment. Roller-compacted concrete (RCC) is the most important development in concrete ...

MAGNESIUM PHOSPHATE CONCRETE

Magnesium Phosphate ConcreteMagnesium phosphate concrete (MPC) is based on a cementitious system that is different from Portland cement. Rapid repairs of patches may be economically achieved by MPC. It has high bond strength and low shrinkage rates. Setting times of ...

POLYMER-CEMENT CONCRETE

Polymer-Cement ConcretePolymer-cement concrete (PCC), also called polymer-Portland-cement concrete (PPCC) and latex-modified concrete (LMC), is made ...

DEPOLLUTANT PHOTO-CATALYTIC CONCRETE (DPCC)

The word photocataysis is a compound word made up of (1) photo or light and (2) catalysis or acceleration of a chemical reaction rate by addition of a catalyst. A catalyst is a substance which although combines with the reactants ...

GREEN CONCRETE

WHAT IS GREEN CONCRETE? Today the word green is not just limited to colour, it represents the environment, which is surrounding us. Concrete which is made from concrete wastes that are eco-friendly are called as “Green concrete”. The other name for green concrete ...

PERVIOUS CONCRETE: FUTURISTIC SOLUTION TO URBAN RUNOFF?

Pervious concrete is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge. ...

HOT WEATHER CONCRETING

Placing Concrete in Hot Weather Caution needs to be applied when placing concrete in hot weather. Without the proper care, concrete may have reduced strength and will be very prone to cracking due to rapid drying. It also may stiffen quickly ...

COLD WEATHER / WINTER CONCRETING

Placing Concrete During Cold Weather If the temperature of fresh concrete is 55ºF., or greater — and if the concrete is maintained at a temperature of 55ºF. or higher — then winter concreting should be trouble-free. Approximate set time for concrete ...

STACKED LOG CONSTRUCTION

Log houses originated in Europe where they were hastily erected as hunting cabins. Stacked log homes today are elaborate structures worth several hundred thousand dollars in some cases. Coniferous trees are ideal for constructing stacked log houses are the timber ...
