Impact of High Temperature to Aluminous Cement Based Fibre Cement Composites Containing Polycarboxylate Superplasticizer

Popis výsledku v původním jazyce

This paper summarizes the results of an experimental program focused on investigation of the mechanical properties of composites based on aluminous cement for high-temperature applications and deal with the influence of high-thermal loading on polycarboxylate superplasticizer (PCSP) contained in the composite. The intent of performed examination was caused by the suspicion that the action of high-temperatures can lead to burnout of the PCSP additive and thus subsequently affecting the mechanical properties of the final composite. Composites based on Portland cement and silica aggregates are not able to resist the action of high-temperatures. For high-temperature composites was therefore used aluminous cement Secar71 (Lafarge S.A.) in combination with crushed basalt aggregates of fraction 0/4 and 2/5 mm. The flexural strength was increased thanks to the combination of basalt fibers with lengths of 6.35 mm and 12.7 mm. The values of flexural and compression strength were investigated on
