Preliminary study on concrete with Polystrene waste coarse aggregate
(2007)
Polystrene wastes are becoming a major environment concern; due to its large production quantities and its non-biodegrable nature. Provided that the high molecular-weight material can be broken down into useful low ...

Several experiments were conducted
to characterize the properties of modified
polystyrene lightweight aggregate in concrete.
Microstructure of modified polystyrene
lightweight aggregate in concrete can be assessed
by ...
Effects of elevated temperatures on the thermal behavior and mechanical performance of fly ash geopolymer paste, mortar and lightweight concrete
(Elsevier, 2014-01)
This paper reports a comparative study of the influence of elevated temperature on geopolymer paste, mortars and lightweight aggregate geopolymer concrete (LWAGC) systems made by using fly ash (FA) as only source material. ...
Microstructure study on optimization of high strength fly ash based geopolymer
(Trans Tech Publications, 2012)
The compressive strength and microstructural characteristics of fly ash based geopolymer with alkaline activator solution were investigated. The sodium hydroxide and sodium silicate were mixed together to form an alkaline ...
Preliminary study on compressive strength of modified Polystyrene (MPS) as lightweight aggregate
(Universiti Malaysia Perlis, 2008-03-15)
This research investigates the possibility of making polystyrene as lightweight aggregate. Low density is the advantage of polystyrene. Waste polystyrene foam is modified and sintered in the furnace at the temperatures ...
Image analysis of surface porosity mortar containing processed spent bleaching earth
(MDPI AG, 2021-03-28)
Image analysis techniques are gaining popularity in the studies of civil engineering materials. However, the current established image analysis methods often require advanced machinery and strict image acquisition procedures ...
Contribution of interfacial bonding towards geopolymers properties in geopolymers reinforced fibers: a review
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-02-17)
There is a burgeoning interest in the development of geopolymers as sustainable construction materials and incombustible inorganic polymers. However, geopolymers show quasi-brittle behavior. To overcome this weakness, ...
Bonding strength characteristics of FA-based geopolymer paste as a repair material when applied on OPC substrate
(MDPI AG, 2020-05)
This investigative study aims to study the mechanical and morphological properties of fly ash (FA)-based geopolymer paste as a repair material when applied on ordinary Portland cement (OPC) overlay concrete. The first part ...
Comparison of geopolymer fly ash and ordinary Portland cement to the strength of concrete
(American Scientific Publishers, 2013-12)
The aim of this study is to evaluate the effect of various fly ash: aggregate ratios by using fly ash (FA) based geopolymer compared to ordinary Portland cement (OPC) on the compressive strength of concrete. The different ...
Mechanical properties and wear behavior of brake pads produced from palm slag
(Trans Tech Publications, 2012)
Brake pads are important safety devices in vehicles. An effort to avoid the use of asbestos in brake pads has led to the development of asbestos-free brake pads that incorporate various organic and inorganic fillers. Palm ...
