In this research, a study is made on the Pervious Geopolymer Concrete (PGC), which based local material (Metakaolin). The inclusion of Ordinary Portland Cement (OPC) as partial substitute for Metakaolin (MK) production (PGCs) has also been investigated. concrete was outputted from (MK), and ordinary cement by weight MK silicate sodium (Na2SiO3) hydroxide (NaOH) solution. All PGC samples were cu...

Geopolymer concrete has been developed as a replacement for conventional with other pozzolan materials, which have high silicate alumina content. Fly ash is material that contains of 22%. The content Al and Si increases the compressive strength concrete. High-calcium fly abundantly found in Indonesia. However, it not widely used industry or research, this due to fast hardening time Therefore, p...

Abstract In many crucial structural applications, a material’s ability to withstand impact is of the utmost importance. The use crumb rubber particles as partial replacement natural aggregates forms rubberized geopolymer concrete (RuGPC), which found have great resistance and energy absorption capacity. Geopolymer paste alone are weak in handling loads. field Civil engineering has been looking ...

The objective of this research is to investigate the possible reuse dredged sediments from port Cherbourg, France, as an alternative material in road engineering and a backfill material. These contain high percentages organic matter (OM), presence OM sediment, even small amounts, can affect properties sediments. This was carried out two series: sediment treated with traditional hydraulic binder...

Unfortunately, the production of cement impacts pessimistically on environments since it emits CO2—a principal Green House Gas (GHG)—encouraging earth-heating dilemma. Moreover, necessitates not only high temperature produced by devouring narrow natural mineral coal resources to obtain very amounts energy, but also gulps down limestone deposits as a raw material that is found confined in nature...

Nowadays, concepts of self-cleaning have received great attention in construction building materials. Self-cleaning with the presence photocatalyst has been applied materials to overcome problem surfaces becoming dirty after exposure for a long time highly polluted areas. To date, concept green blending led development new binding material materials, which is geopolymer an addition photocatalys...

Researchers have been driven to investigate sustainable alternatives cement production, such as geopolymers, due the impact of global warming and climate change resulting from greenhouse gas emissions. Currently, they are exploring different methods waste materials enhance mechanical physical properties geopolymer expand its application range. This review paper offers a thorough analysis utiliz...

The production of Portland cement is energy-intensive and polluting. As a result, the search for ecological economical alternatives has become global priority. Geopolymers are among most promising to cement. Their properties depend on nature concentration activators. This study investigates effect Na2SiO3/NaOH ratio NaOH molarity alkaline activation natural volcanic pozzolan. physico-mechanical...

Geopolymer composites have been around only for 40 years. Nowadays, they are used in buildings and infrastructures of various kinds. A geopolymer’s main benefit is that it a green material partially made by utilizing waste products. The carbon footprint from geopolymer matrix manufacturing at least two times less than Portland cement manufacturing. Due to the nature process, there high risk shr...

Geopolymer cement (GPC) is an aluminosilicate-based binder that cost-effective and eco-friendly, with high compressive strength resistance to acid attack. It can prevent degradation when exposed carbon dioxide by virtue of the low calcium content aluminosilicate source. The effect concentration chloride (CaCl2) as accelerator on acoustic impedance GPC for well cement, while pressure temperature...
