Properties of Modified High Permeable Concrete with a Crumb Rubber

Abstract

Background: High permeable concrete is designed with high porosity, which allows water to pass through it. By considering this ability, it has been widely used for various applications including high permeable road pavement. However, to fully adopt highly permeable road pavement technology is challenging due to high cost and maintenance, besides the present engineers and contractors have insufficient expertise and experience with this technology. Henceforth, the high porosity property is highly favorable for road curb applications especially in the tropical region like Malaysia with high rainfall intensity. Objective: This paper aimed to determine the properties of the concrete experimentally, and propose the optimum mix design of high permeable concrete for road curb. Methods: The flow value and setting time of the cement paste were investigated. Next, the effects of the modified high permeable concrete with varying amount of crumb rubber on compressive strength, permeability and void ratio were also investigated. Results and Conclusion: Results have revealed that the workability of the cement paste increases when the water-binder ratio and the amount of fly ash increase. Meanwhile, an increasing amount of cement ratio and crumb rubber lowers the flow value and consequently leads to lower void ratio and permeability. Besides, it has been found that the higher the compressive strength, the lower the void ratio and permeability of the concrete. The research findings support that using an optimum amount of cement replacement with crumb rubber as an additive may increase the performance a high permeable concrete. Herein, the results indicate that the mix design of the concrete studied has the potential to be applied onto the road curb.

Deformation Properties of Rubberized ECC Incorporating Nano Graphene Using Response Surface Methodology

“…Therefore, graphene motivated vast investigation interests due to its impressive characteristics, aiming at the discovery of new innovative nanomaterials in this construction era, with its application in ECC intriguing numerous scientists worldwide [ 39 , 40 ]. It is reported that the incorporation of rubberized ECC with GO revealed that the use of coarse crumb rubber is lower than the use of fine crumb rubber [ 41 ]. This indicates that the upsurge in the volume of crumb rubber marginally reduces the strength and penetrability in the concrete mass; thus, this developed mixture of rubberized ECC integrated with GO can be potentially used in the fabrication of several construction materials for applications such as road pavement/basement and filling voids, while it also enhances the freeze–thaw resistance and ductility [ 33 ].…”

The development of permeable pavement from demolished construction waste

“…Based on their ability to absorb water, paving blocks are divided into two categories, namely low permeable paving blocks and high permeable paving blocks. Paving blocks can be categorized as high permeable if they have an infiltration rate of more than 3 mm/s [5].…”

A review of factors influencing performance of pervious concrete

“…Higher w/cm ratio results in an increased workability of the cement paste, which can also be obtained at low w/cm ratios by using superplasticizers [7].…”

“…Voids present in pervious concrete systems have been found to absorb sound quite efficiently [55]. Ng et al [7] recommend the void content of pervious concrete ranging from 15 % to 25 % as the acceptance criterion for ensuring the quality of concrete. Figure 5 shows the range of porosities adopted by previous researchers.…”

“…However, this also engenders a decrease in density ranging from 1600kg/m 3 to 2000 kg/m 3 [4] and compressive strength of 2.8 to 28 MPa [5,6]. As to its application, pervious concrete can be used in the construction of pervious pavements or floors for sidewalks, parking lots and pavement curb applications [7], overlays in some pavement systems [1], airport fields [8], base course for heavy traffic pavements [1], tennis courts [6], swimming pool decks, embankments, animal barns, stone protection structures [9], etc. Luck et al [10] determined that pervious concrete can be effectively used for the separation of solids and liquids in agriculture.…”
