With a complete understanding of the condition of the existing slab, the surface can be repaired and prepared, and issues can be mitigated to comply with the requirements of the new flooring system. The flooring system manufacturer should be consulted when selecting repair materials and evaluating the surface to be coated.

Analysis on gold tailings-based aerated concrete in different phases of autoclave curing based on nuclear magnetic resonance / Qian Li in REVUE DES COMPOSITES ET DES MATERIAUX AVANCES, Vol. 29, N° 6 (12/2019)

Langues : Français (fre) Catégories : Béton cellulaire Matériaux cimentaires -- Analyse Or Résonance magnétique nucléaire Index. décimale : 620.13 Matériaux de construction : pierre, ciment, béton, liants de Résumé : This paper prepares an aerated concrete (AC) with gold tailings as the main material, and explores the influence of different phases of autoclave curing on the microstructure of the proposed AC. Three specimens were selected for nuclear magnetic resonance (NMR) tests: the specimen not autoclaved after the 12h static curing, the specimen autoclaved for 0h in the autoclave (i.e. only heated up and cooled down), and the specimen autoclaved for 8h under constant temperature. The three specimens are denoted as NAC, AAC-0 and AAC-8, respectively. The internal structures of the specimens in each phase of autoclave curing were analyzed through 27Al NMR and 29Si NMR tests. The results show that the Si-O tetrahedrons in the AAC-8 specimen mainly exist in the form of Q2 structures ; the 1.1nm tobermite crystal is a chain silicate. The research results help to reveal the reaction mechanism of the AC in each phase of curing, and improve the performance of gold tailings-based AC.

Experimental investigation of rubberized functionally graded in REVUE DES COMPOSITES ET DES MATERIAUX AVANCES, Vol. 31, N° 1 (02/2021)

The engineering properties of structures can be enhanced by using different concrete grades in the same structural element based on its specific requirement in functionally graded concrete (FGC). For meticulous critical inspection, an experimental investigation was prosecuted on three different types of concrete (conventional concrete (CC), rubber fiber concrete (RFC) and rubberized functionally graded concrete (RFGC)), and their properties were compared. The fine aggregate was substituted (by volume) with waste rubber fiber by 5, 10, 15, 20 and 30% to prepare RFC and RFGC. Tests were performed on concrete samples to analyze compressive strength, flexural strength, water permeability, and drying shrinkage. Moreover, scanning electron microscopy (SEM) was utilized to observe the microstructures. Results indicated that RFGC performed better than CC and RFC and can be used to prepare precast structures and for the applications where high flexural load acts.
