EFFECT OF CRACK-REDUCING TECHNOLOGIES AND SUPPLEMENTARY CEMENTITIOUS MATERIALS ON SETTLEMENT CRACKING OF PLASTIC CONCRETE AND DURABILITY PERFORMANCE OF HARDENED CONCRETE
… durability, based on ASTM C666 Procedure B, scaling resistance, based on a modified version of Canadian Test BNQ NQ 2621-900 Annex B, and characteristics of the air-void system, obtained following ASTM C457. The research also examined the correlation between air-void characteristics, …

Visualizing mixed variable-type multidimensional data using tree distances
… of most variable types, indifference to variable scaling, resistance to noise and outliers, accommodations for missing values, and computational ease. In this research, we map the dissimilarities using Classical Multidimensional Scaling to a lower-dimensional Euclidean space in order to provide an …

Freeze-Thaw Resistance and Microstructural Characteristics of Concretes Containing Pozzolans
… Based on a criterion that unsatisfactory resistance to freezing and thawing corresponds to a durability factor (DF) less than 60% or a change in length greater than 200 μm/m, all the air-entrained concretes exhibited excellent performance under freeze-thaw conditions irrespective of the MK …

Steam Cured Self-Consolidating Concrete and the Effects of Limestone Filler
… chloride permeability, linear shrinkage, sulfate resistance, freeze-thaw resistance and salt scaling resistance) of various self-consolidating concrete mix designs containing 5% silica fume and steam cured at a maximum holding temperature of 55°C. This research also examines the resistance to …

Development of Modified Reverse Osmosis Membrane with Polymers/Graphene Oxide for Scaling and Biofouling Mitigation
… however, operational challenges such as scaling and biofouling hinder membrane performance, reducing water flux and increasing maintenance costs. This study uniquely explored, the dual antifouling and antibiofouling properties of polymaleic acid (PMA) in an RO system. PMA was applied in …

Influences on durability and leaching behaviour of concrete: new technologies in fly ash production
… finer, low LOI fly ashes had higher chloride resistance and at equal strength fly ash concretes performed better than those with PC. Equal strength fly ash concretes covering the modern technologies were found to have similar levels of durability for sulfate attack, abrasion and carbonation. …

EFFECTS OF DEICING SALTS ON THE DURABILITY OF CONCRETE INCORPORATING SUPPLEMENTARY CEMENTITIOUS MATERIALS
… based on damage due to wetting and drying and scaling, with the goal of determining appropriate replacement levels of portland cement using these SCMs. The mixtures had water-to-cementitious material ratios of 0.38 and 0.44 and SCM percentage replacements of portland cement of 0%, 20%, 35%, and …
