Direct Relation

The aim of the study is to investigate compressive strength of pervious concrete by reduction of fine aggregate from zero to 100%, additionally investigate infiltration rate of pervious concrete. Experimental study has conducted at Cecos Engineering University Peshawar. The pervious concrete samples were produced for 7 and 28 days. Compressive strength of pervious concrete indicated higher reduction of the sand reduces compressive strength and almost 50% compressive strength decreased by reduction of 100% sand from the design mix. On the other side, infiltration rate for 28 days shows direct relation above 40% reduction of sand and highest 273% of infiltration rate by reducing 100% sand from the design mix. The 90% reduction of sand from concrete give considerable compressive strength of 2150 psi and infiltration rate of 165.79 inch/hour, which can be recommended for pavements of parking and walking area.

Alternative Solutions

ABSTRACTThe application of pervious concrete has been increasing in the area of civil engineering to be one of the alternative solutions in reducing stormwater run-off and prevents flooding. This research aims to investigate the compressive strength and permeability of pervious cement concrete with various of cement:aggregate ratio = 1:2, 1:4 and 1:6, and at a water cement ratio of 0.3. The proportion that obtained highest compressive strength at 7 days was then selected to investigate the effect of superplasticizer addition in pervious concrete based on the results of compressive strength test at 7, 14 and 28 days, and void ratio test at 7 and 28 days. The infiltration rate test was also conducted according to ASTM C1701-standard to analyse the permeability level of pervious concrete with and without superplaticizer. The results show that the optimum compressive strength of pervious concrete at 7 days peaked at 5.67 MPa, reached by the mixtures with cement:aggregate ratio = 1:2. The addition of 0.5% superplasticizer by weight of cement in this mixture was found effective in improving the compressive strength of pervious concrete up to 8.51 MPa, 10.92 MPa and 13.47 MPa at 7, 14 and 28 days, respectively. It can be concluded that the use of superplasticizer has an effect in increasing the bonding between aggregate-paste and therefore, improves the compressive strength and balance the permeability properties of pervious cement concrete.Key words : Pervious concrete, compressive strength, void ratio, permeability, superplasticizerABSTRAKAplikasi beton berpori semakin mendapat perhatian di bidang Teknik Sipil karena dapat dijadikan sebagai salah satu solusi untuk mengurangi limpasan air hujan dan mencegah banjir.

Industrial alkali slag is the discharge waste in the process of alkali production. About one million tons of alkali slag is discharged in China in one year. It is a burden on the environment, whether it is directly stacked or discharged into the sea. If we can realize the use of resources, it is a multi-pronged move, so alkali slag is used to improve solidified marine soft soil in this paper. The test results show that the alkali residue can effectively improve the engineering properties of marine soft soil. Among them, the unconfined compressive strength and compressive modulus are increased by about 10 times, and the void ratio and plasticity index can all reach the level of general clay. It shows that alkali slag has the potential to improve marine soft soil and can be popularized in engineering.

Abstract: Pervious concrete is a special type of concrete, which consists of cement, coarse aggregates, water and if required and other cementations materials. As there are no fine aggregates used in the concrete matrix, the void content is more which allows the water to flow through its bodyThe main aim of this project was to improve the compressive strength characteristics of pervious concrete. But it can be noted that with increase in compressive strength the void ratio decreases. Hence, the improvement of strength should not affect the porosity property because it is the property which serves its purpose. In this investigation work the compressive strength of pervious concrete is increased by a maximum of 18.26% for 28 days when 8% fine aggregates were added to standard pervious concrete Keywords: W/C ratio, pervious Concrete, sugarcane bagasse’s ash, rice husk ash compressive strength, fine aggregates

Flooding is one of the climatic change consequences that has become a dangerous threat to many coastal cities. Pervious concrete is considered a solution to decrease rainwater runoff and mitigate flood effects, as it allows water to percolate through the ground and prevent possible damage. Using waste products as aggregates in pervious concrete not only exploits waste materials and makes it valuable but also reduces the amount of this waste ending in the landfill or harming the environment, and it decreases the demand for natural resources. Infiltration rate test and compressive strength tests were conducted to investigate the effect of using waste plastic and/or recycled rubber as concrete coarse aggregates with different ratios (5%, 10%, 15%, 20%, and 25%) on the pervious concrete. The results showed that increasing the waste materials in concrete decreased the compressive strength for all ratios while increased the infiltration rate values.

This paper presents the experimental results on the effect of metakaolin (MK) as a replacement of cement in pervious cement concrete based on compressive strength, void ratio and permeability test. Metakaolin was used to replace Portland Cement Composite (PCC) in pervious concrete by 10% (by wt.). The results show that pervious concrete sample containing 10% metakaolin with 1% superplasticizer exhibited 4 times higher compressive strength at 7 days when compared to normal cement concrete. In addition, the continuous voids of 10%MK concrete sample was found higher than PCC only, indicating the effectiveness of metakaolin in improving the interfacial bond of the binders due to micro-filler effect of metakaolin and the additional CSH gel formation. The continuous voids of pervious concrete with 10% MK is 17%, which is higher than the percentage of continuous voids in normal pervious concrete. This finding is also supported by the infiltration rate of concrete samples. Furthermore, the microstructure analysis through Backscattered Electron Imaging and X-Ray Diffraction reported denser matrix and CH reduction in polished paste samples due to 10%MK addition.

Abstract Porous concrete is an amalgamation of coarse aggregate, Portland cement, and water, which permits rainfall water to permeate through the surface and into the ground before it runs off. Porous concrete encompasses little or no fine aggregates and adequate cementitious fixative to coat the coarse aggregate while keeping the voids interconnected. IRC 44-2017 states that range of permeability for pervious concrete should be from 0.135 cm/second to 1.22 cm/second and array of compressive strength should be 5MPa - 25MPa. In this experimental study, two properties of no fine concrete namely compressive strength and porousness at the curing age of 7th & 28rd days has been targeted. Compressive strength and Infiltration tests were conducted on the pervious concrete of grade M10 and M15 by keeping variation of fine aggregates of 0% - 5%. We observed that fines aggregate help to rise the compressive strength of porous concrete but decrease the permeability. Thus, by careful optimization of the mix, pervious concrete can be obtained for suitable use in low strength load.
