Along with the development progress in Indonesia, it causes reduction of green areas. Coupled lack public awareness environment is a problem that must be considered. Pervious concrete as one solutions pavement construction, sheet piles, retaining walls product can considered successfully meeting expectations an environmentally friendly construction. For road pavement, pervious have strength 30 ...

Abstract Due to the high demand for natural aggregates in pavement construction, researchers have been looking alternative materials replace aggregate. In this research, optimum binder content of asphalt mixture incorporate limestones was investigated. The tested according Marshall method. About 20 % limestone used as aggregate replacement asphaltic concrete mixture. To determine stability, vol...

Cracks are a fundamental problem in concrete, so this research investigates an experimental study of the effect adding SiO2 on self-healing behaviour concrete. The is done by studying physical properties, microstructure, and mechanical properties Microcapsules were prepared to contain (cement nano SiO2) (palettization (fluidize bed coating) method) with (5,10, 15) % cement weight. ratio concret...

In conventional concrete, micro-cracks develop before structure is loaded because of drying shrinkage and other causes of volume change. When the structure is loaded, the micro cracks open up and propagate because of development of such micro-cracks, results in inelastic deformation in concrete. Fibre reinforced concrete (FRC) is cementing concrete reinforced mixture with more or less randomly ...

In concrete pavements, a single concrete mixture design is selected to resist mechanical loading without attempting to adversely affect the concrete pavement shrinkage, ride quality, or noise attenuation. An alternative approach is to design distinct layers within the concrete pavement surface which have specific functions thus achieving higher performance at a lower cost. The objective of this...

Incorporating superabsorbent polymer (SAP), which has the abilities of absorption and desorption in concrete can achieve the effect of internal curing. The influences of the volume, particle size and ways of entrained water of SAP on the workability, compressive strength, shrinkage, carbonation resistance and chloride penetration resistance of concrete were analyzed through the macroscopic and ...

Cold region covers over 50% all the world. As an indispensable part of project, concrete is greatly affected by temperature during curing process. In this paper, through orthogonal experiment design, we studied mixing temperature, steel fiber, and water reducing agent dosage on mixture slump; influence agent, accelerating content compressive strength concrete; final microstructure scanning elec...
