Investigating properties of pervious concretes containing coconut shell flake and ash

Evaluation of Coal Waste Ash and Rice Husk Ash on Properties of Pervious Concrete Pavement

The use of pervious concrete has been significantly considered in recent years. This consideration is due to the properties of pervious concrete in relating to the environmental sustainability that is utilized in the effective management of the runoff from rainfall. Coal extraction and rice husk obtained from milling, produces wastes that have no application and followed by environmental pollut...

Thermal Properties of High-Volume Fly Ash Mortars and Concretes

As sustainability moves to the forefront of construction, the utilization of high volume fly ash concrete mixtures to reduce CO2 emissions and cement consumption per unit volume of concrete placed is receiving renewed interest. Concrete mixtures in which the fly ash replaces 50 % or more of the portland cement are both economically and technically viable. This paper focuses on a characterizatio...

Investigating the Physical Properties and Runoff Treatment Capability of Pervious Concrete Containing Granular Activated Carbon

Predicting the Permeability of Pervious Concretes from Planar Images

This paper discusses the reconstruction of three-dimensional material structures of pervious concretes using two-dimensional digital images obtained from actual specimens, and computational permeability predictions using these reconstructed three-dimensional material structures. The computer programs developed at the National Institutes of Standards and Technology (NIST) are used to obtain thre...

Fly ash/Kaolin based geopolymer green concretes and their mechanical properties

Geopolymer concrete mixes were cast using fly ash, kaolin, sodium hydroxide, potassium hydroxide, sodium silicate and aggregates. Portland cement concrete (M30) was used as a reference sample. The effect of silica fume, temperature (40 °C, 60 °C, 80 °C, 100 °C and 120 °C), sodium and potassium hydroxides and different superplasticizers on the compressive strength are reported [1]. Maximum stren...
