Rheological and mechanical properties of alkali-activated brick powder based pastes: effect of amount of alkali activator
(IOP Publishing, 2018-07-12)The rheological behaviour and mechanical properties of alkali-activated materials prepared by activation of a brick powder by alkaline solution (alkali + water glass) is presented in this paper. The effect of quantity of ... -
Rheological and mechanical properties of lime-brick powder mortars with expanded clay aggregate
(IOP Publishing, 2018-07-16)The rheological behaviour and mechanical properties of lightweight lime-brick powder mortars with combined expanded clay-sand aggregates are presented in this paper. The rheological investigation included the characterization ... -
Rheological characteristics of aerial lime-based pastes with addition of biopolymers
(IOP Publishing, 2018-07-16)Viscosity enhancing admixtures are widely used to improve the properties of concrete and ready-mix mortars. This study focuses on the influence of biopolymer (sodium salt of alginic acid, carrageenan, diutan gum, gellan ... -
Rheology of natural hydraulic lime pastes modified by non-traditional biopolymeric admixtures
(SCIENTIFIC SOC SILICATE INDUSTRY-SZTE, 2019-11-29)Viscosity enhancing admixtures, widely used to improve characteristics of concrete and ready-mix mortars, are mainly different derivatives of cellulose. Due to the nature of cellulose processing, the environmental-friendlier ... -
Salt and Ice Crystallization Resistance of Lime Mortars with Natural Lightweight Aggregate
(Scipedia, 2020-09-25)In this study, the comparison of lava sand, pumice, and natural zeolite as lightweight aggregate in air lime mortars, natural hydraulic lime mortars, and cement-lime mortars has been investigated with emphasis on the ... -
Self-Sensing Properties of Fly Ash Geopolymer Doped with Carbon Black under Compression
(MDPI, 2021-08-04)The development of smart materials is a basic prerequisite for the development of new tech-nologies enabling the continuous non-destructive diagnostic analysis of building structures. Within this framework, the piezoresistive ... -
Ternary binder based plasters with improved thermal insulating ability
(IOP Publishing, 2017-10-25)New kind of plasters with improved thermal insulating ability are presented in this article. Improvement was reached by utilization of lightweight expanded perlite with high porosity. The second used aggregate was silica ... -
Thermal behaviour of metakaolin/fly ash geopolymers with chamotte aggregate
(MDPI, 2016-06-30)Geopolymers are generally appreciated for their good resistance against high temperatures. This paper compares the influence of thermal treatment with temperatures ranging from 200–1200 °C on the mechanical properties and ...
