This article focuses on the processes of interaction between calcium silicate hydrates and dispersed polyvinyl acetate in tight films with the aim of developing compounds meant for restoration and finishing works. The basis of this development relies on the concept concerning the determining role of the crystal-chemic…
Realkalisation and electrochemical chloride removal techniques, developed for rehabiliting carbonated and chloride-containing structures, are presented. Electrolysis and electromigration mechanisms and consequences as well as electrochemical conditions at the reinforcement surface are discussed and compared with catho…
Delayed ettringite formation (DEF) is the term used to describe expansion of some heat cured portland cement concretes. Although meaningful progress has been made, the exact mechanism of the expansion itself is not entirely understood. The ettringite reformation is enabled, primarily, by thermal decomposition of ettri…
This paper covers studies made using different mixes for cellular concrete variating silica sand, vulcanic glass and aluminium powder contents. Studies on compressive strenght, dry density and X-ray diffraction are performed on autoclave cured cellular concrete, concluding that best results are attained when vulcanic…
Abstract A series of conducting polyaniline/poly(butadiene‐co‐styrene‐co‐2‐vinylpyridine) (PBSP) latex composites was prepared by polymerization of aniline in the presence of PBSP latex. The mass loading of polyaniline in the composite latex can be controlled by varying the PBSP latex/aniline charging ratio and oxidan…
A differential thermal analysis (DTA) method has been developed that identifies and distinguishes surface and internal (volume) crystallization in glasses. This method is fast, convenient, and requires only a small quantity of sample, ∼500 mg, to identify the dominant crystallization, surface versus internal, in the g…
