Effect of metakaolin pozzolanic activity in the early stages of cement type II paste and mortar hydration
(2008-04-01)
The cement industry is one which most emits polluting gases to the environment, due to the calcium carbonate calcination, as well as to the burning of fossil fuels during the manufacturing process. Metakaolin (MK), in ...
Lightweight concrete masonry blocks produced with: tire rubber and metakaolin
(Pontificia Univ Catolica Chile, Dept Ingenieria & Gestion Construccion, 2020-12-01)
This paper presents the evaluation of lightweight concrete masonry blocks, incorporated with tire rubber and metakaolin, aiming reduce its bulk density and obtaining dimensional values of compressive strength and water ...

Kinetic study of the dissolution of metakaolin with hydrofluoric acid
(National Institute of Science Communication, 2018-05)
The kinetics mechanism on the dissolution of metakaolin by hydrofluoric acid has been studied. The effects of temperature, reaction time, and stirring speed have been examined. Experimental results show that reaction rate ...
Performance evaluation of cement mortars modified with metakaolin or ground brick
(Brasil, 2009)
The work analyzes the performance of mortars prepared with two metakaolin samples and ground calcined-clay brick. Complete stress–strain deformation response under compression, porosity, sorptivity, pore size distribution ...
Evaluation of the long-term compressive strength development of the sewage sludge ash/metakaolin–based geopolymer
(2021-07-28)
This paper aimed to evaluate the long-term compressive strength development of the sewage sludge ash/metakaolin (SSA/MK)–based geopolymer. SSA/MK–based geopolymeric mortars and pastes were produced at 25ºC with different ...
Study on the NaOH/metakaolin Ratio and Crystallization Time for Zeolite a Synthesis from Kaolin Using Statistical Design
(ABM, ABC, ABPol, 2017-04-13)
Use of glass waste in the production of metakaolin-based geopolymer submitted to room temperature and thermal curing
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2021)
Pore structure characterization of kaolin, metakaolin, and their acid-treated products using small-angle X-ray scattering
(1994-02-01)
Pore structure of dealuminated kaolin and metakaolin was studied by small-angle X-ray scattering (SAXS). Both parent kaolin and metakaolin have about 10% of the total pore volume provided by globular pores with 105 Å mean ...
