Characterizations and Industrial Applications for Cement and Concrete Incorporated Natural Zeolite

Abstract

Zeolites have been widely used in various industries, leading to a high commercial value; this is mainly due to the wide diversity of naturally occurring species and the ability to synthesize new types. In the cement and concrete industry, natural zeolite is a popular natural pozzolanic material in some regions of the world owing to their economic, environmental, and technical advantages, among others, used pozzolanic materials. Many works have reported the use of natural zeolite as substituent material for cement in mortar and concrete. Generally, the use of natural zeolite can overcome environmental and economic problems associated with the use of high quantity of cement; furthermore, it is shown a strength enhancement and durability improvement properties of cement and concrete composites. In this context, this chapter strives to review the application of natural zeolite as pozzolan in cement and concrete composites, its characteristic, its proper incorporation, and each of the influencing parameters. In addition, the elaboration methods, textural and mechanical characterization, and applications of these composites will be treated.

High-temperature behavior of zeolite-containing mortar. Experiment and modelling

“…This study focused on thermal behavior, which was tested to be, generally, better for mortars containing zeolites [9]. On the other hand, Uzal and Turanli [10] experimentally showed that cements containing clinoptilolite tuff have less pores larger than 50nm when compared to ordinary Portland cement specimens, which means a higher probability for the appearance of exfoliation.…”
