The setting time of concrete is mainly related to the setting time of cement, and the aggregate has little effect, so the setting time of mortar can be used instead of studying the effect of HP cellulose on the setting time of underwater non dispersible concrete mixture. Since the setting time of mortar is affected by water cement ratio and cement sand ratio, in order to evaluate the effect of HP cellulose on the setting time of mortar, it is necessary to fix the water cement ratio and cement sand ratio of mortar.
Due to its high degree of methoxylation, MHEC is the only cellulose derivative with the best water retention, which is the only reason why MHEC is sold for use in cement-based wall putties and mortars. MHEC is also used in cement-based tile adhesives and grouts.
