With rapid urban development, natural aggregate resources have become scarce and a large number of ageing buildings are being demolished, which has resulted in significant reduction increase construction waste. Therefore, the reuse solid waste, including waste powder recycled aggregate, attracted more attention. Additionally, as prominent way to alleviate heat island effect manage stormwater ru...

Abstract To mitigate environmental challenges, such as urban flooding, noise pollution, and the heat island effect, pervious concrete has been developed. This research was intended to develop made from ground granulated blast furnace slag (GGBFS) further decrease impact of construction sector by reducing content ordinary Portland cement (OPC). The primary objective mix proportion maximize water...

In recent years, China has entered a period of rapid urban development, but most the cities with development still have ground hardening, which makes it difficult for rainwater to penetrate and discharge. order achieve drainage accumulated water in city, nanotechnology was introduced, permeable concrete based on NC NS nanomaterials proposed. Combined finite element analysis, properties mechanic...

Abstract Compaction is a fundamental step in pervious concrete production and affects its mechanical hydraulic properties. In this study, two mixtures were compacted with three different energies, distributed layers. The effects on porosity, strength conductivity evaluated. increase compaction energy resulted proportional reduction porosity. Increases compressive from 17 to 36% observed. Howeve...

This study was conducted to address practical problems in producing structural pervious concrete, such as issues with mix proportioning, paste sagging, porosity, strength, and acoustic absorption. Concrete mixtures varying aggregate types, target void ratios, fiber contents were cast cylindrical panel-type specimens determine the compressive absorption coefficient. Porosities of concrete measur...
