Effect of Mix Proportions on Rheological and Hardened Properties of Composite Cement Pastes
There is an increasing need to identify the effect of mix composition on the rheological properties of composite cement pastes using simple tests to determine the fluidity, the cohesion and other mechanical properties of grouting applications such as compressive strength. This paper reviews statistical models developed using a fractional factorial design which was carried out to model the influ...
متن کاملUniformly Dispersed and Re-Agglomerated Graphene Oxide-Based Cement Pastes: A Comparison of Rheological Properties, Mechanical Properties and Microstructure
The properties of graphene oxide (GO)-based cement paste can be significantly affected by the state of GO dispersion. In this study, the effects of uniformly dispersed and re-agglomerated GO on the rheological, mechanical properties and microstructure of cement paste were systematically investigated. Two distinct dispersion states can be achieved by altering the mixing sequence: Polycarboxylate...
متن کاملTechnology of Polymer-cement Mixes Preparation with Specified Rheological Properties Technology of Polymer-cement Mixes Preparation with Specified Rheological Properties
In recent years, many new materials appeared on our construction market: polymer pastes, sealants, primers, foam. In addition, dry mixes have been suffered some changes. Previously, for the bonding of stones, leveling and processing of walls and ceilings lime, clay, alabaster, gypsum, and mixtures were used. Before the use, they are diluted with water. The development of dry mixes conducted in ...
متن کاملProperties of Cement Pastes Doped with Very High Amounts of Ground Granulated Blast-furnace Slag
In the current work, the properties of cement pastes doped with high amounts of ground granulated blast-furnace slag (HVS) were investigated. Portland cement (PC) was substituted with ground granulated blast-furnace slag (donated as slag) at very high amounts of 85%, 90%, 95% and 100%, by weight. PC paste without any content of slag was used as a reference. Some fresh and hardened properties su...
متن کاملPolyelectrolyte Effects on the Rheological Properties of Concentrated Cement Suspensions
Polyelectrolyte species, known as superplasticizers, dramatically affect the rheological properties of dense cement suspensions. We have studied the influence of sulfonated naphthalene formaldehyde condensate (SNF) and carboxylated acrylic ester (CAE) grafted copolymers of varying molecular architecture on the surface (e.g., adsorption behavior and zeta potential) and rheological properties of ...
