Analysis of Structure Formation Peculiarities during Hydration of Oil-Well Cement with Zeolitic Tuff and Metakaolin Additives

Abstract

Investigations concerning the processes of plugging stone structure formation, using X-ray diffraction, electronic microscopy and differential thermal analyses, were implemented. Influence of active mineral additives of metakaolin and zeolite on the properties of plugging mortar and their interaction with Portland cement minerals with the aid of the model systems were established.

Development of nanomodified rapid hardening clinker-efficient concretes based on composite Portland cements

“…However, the issues related to slow rate of early strength gain in concretes with composite cements remain unresolved [16]. This is caused by low reactivity of mineral additives in the cementitious matrix compared to Portland cement clinker phases.…”

Hydrochloric and Orthophosphoric Acids Use in the Quick-Traffic Slurry Surfacing Mix

“…Slurry surfacing mix forms a characteristic surface with better water resistance and adhesive qualities. It can be used on asphalt or concrete road surfaces [1][2][3][4].…”

Performance of Low Carbon Modified Composite Gypsum Binders with Increased Resistance

“…The use of composite cements with a high content of active mineral additives of hydraulic and pozzolanic action provides significant reserves for reducing energy intensity and the carbon footprint of such binders. The high activity of ultrafine natural zeolite tuffs in the binding of lime and gypsum to the hydrated phases opens up the possibility of their effective use in composite cements [12][13][14][15]. Therefore the hydraulic properties of gypsum binders at the present level may be also provided by physico-chemical modification of their properties by means of organomineral additives of polyfunctional action, which have several positive effects due to a synergistic combination.…”
