Analysis of Strength Parameters of Paving Blocks with inclusion Sea Sand

Abstract

Start with the Scarcity of materials in concrete so sand has steadily gained prominence as the most frequent building material used in the construction industry. As the population increases, so does the need for residential and commercial space. The most essential resource for mankind, river sand, is being mined out of riverbeds more frequently. One ton of regular Portland (OPC) cement is produced in India for every tonne of CO2 that is released into the environment. By substituting cementitious materials like fly ash and ground-granulated blast furnace slag for ordinary cement, we can lower the number of greenhouse gases that are emitted into the atmosphere. To create sustainable concrete pavement blocks, this experimental work has been carried out with the use of cementitious elements including fly ash and ground granulated furnace slag (GGBS) as a replacement for cement, and to enhance public transportation, this research is focused on creating paver blocks that contain sea sand as fine aggregate. This experimental investigation was conducted to investigate different sustainable concrete strength properties with 0% sea sand, 50% Sea Sand and 50% M sand, and 100% sea sane used to partially replace the mix proportion. Results of mechanical parameters such as Compressive strength, water absorption, abrasion resistance, and carbonation of these sustainable concrete pavement blocks are presented also a cost analysis of paving blocks was evaluated.
