TL;DR: In this article, the performance of concrete mixtures incorporating 5%, 7.5% and 10% of discarded tyre rubber as aggregate and cement replacements was investigated, and the results showed that with up to 5% replacement, in each set, no major changes on concrete characteristics would occur, however, with further increase in replacement ratios considerable changes were observed.

TL;DR: In this article, three different AWF types including bagasse, wheat and eucalyptus fibres were used to produce Fibre Cement Boards (FCB) and the effect of silica fume on flexural behaviour characteristics of FCB has been studied.

TL;DR: In this article, the flexural behaviour of different amounts of fibre content (1−14%) in cement boards reinforced by waste cardboard was investigated and the optimum fibre content of 8% to achieve the highest flexural strength was determined.

TL;DR: In this article, the effect of incorporating cellulose fibres and silica fume into low-density oil well cement was investigated through various tests including; triaxial, flexural, tensile and compressive strength, cement sheath equivalent, permeability, mercury intrusion Porosimetry, ATR-FTIR analysis, degree of hydration and scanning electron microscopy.

TL;DR: In this paper, the compressive strength and microstructure of calcined clay based geopolymer mortars activated by two forms of sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) solutions were studied and reported.
