“…al. [71] found that with the addition of biomass pieces, shrinkage was higher due to the loss of free water and voids remaining inside concrete. The high variation of properties of natural materials is an additional disadvantage which could lead to unpredictable properties of concrete [9,86,112].…”

International audienceThe use of plant biomass for developing energy efficient and low cost construction materials is an emerging field in building construction and civil engineering. Although the biomass-based cement and concrete composites have several advantages, such as low densities, low amount of CO2 gas emission, good thermal and acoustic insulation, there are also disadvantages or open questions like the durability of biomass in alkaline cement matrix, the high absorption of water and the cement-biomass compatibility, all deteriorating concrete mechanical properties, which are already intrinsically low due to the low mechanical properties of biomass-based fillers. This review gives the necessary basis in plant structure and composition for understanding how and why many treatments tested on biomass for overcoming the above-mentioned difficulties are acting. This paper reviews research papers and patents on the treatments tested to improve the mechanical properties, durability and compatibility of biomass for its use as concrete fillers for building materials

“…al. [71,73] treated wood shaves by spraying a paste of binder, including cement, lime and cement-lime pastes, on the shaves. Among these coatings, cement was the one giving the best results and this technique was previously claimed in two patents by Mouly [135][136][137].…”

“…This kind of concrete has strength comparable with conventional Portland cement concrete. By definition, sand concrete is therefore defined as a fine aggregate concrete, in which coarse aggregate is replaced by sand and fine aggregate is by filler material (Bederina et al 2012;Bederina et al 2007;Khay et al 2010). High performance finegrained concrete (HPFGC) is considered as a new generation of sand concrete, and can be comparable with high performance concrete in strength and durability.…”

Rice husk ash (RHA) is classified as a highly reactive pozzolan. It has a very high silica content similar to that of silica fume (SF). Using less-expensive and locally available RHA as a mineral admixture in concrete brings ample benefits to the costs, the technical properties of concrete as well as to the environment. An experimental study of the effect of RHA blending on workability, strength and durability of high performance fine-grained concrete (HPFGC) is presented. The results show that the addition of RHA to HPFGC improved significantly compressive strength, splitting tensile strength and chloride penetration resistance. Interestingly, the ratio of compressive strength to splitting tensile strength of HPFGC was lower than that of ordinary concrete, especially for the concrete made with 20 % RHA. Compressive strength and splitting tensile strength of HPFGC containing RHA was similar and slightly higher, respectively, than for HPFGC containing SF. Chloride penetration resistance of HPFGC containing 10-15 % RHA was comparable with that of HPFGC containing 10 % SF.

“…Lightened concrete is used for rehabilitation works and non-structural elements, such as those used in non-load bearing walls and thermal insulation [3]. The introduction of plant fibres into different matrices was the subject of several studies aiming at solving several problems related to the thermal and acoustic characteristics, as well as their renewable aspect [4]. The effect of the addition of wood chips on the thermal conductivity of sand concretes with the chip content ranging from 0 to 100 Kg/m3 was studied by Bederina et al (2007) [5], whose results show a reduction in its density and an improvement of its thermal conductivity.…”

The introduction of treated plant fibres into sand concretes leads to a reduction in density, improved ductility and thermal conductivity, and makes sand concrete an environmentally friendly and ecological material. The recovery of waste in this type of material allows the production of new ecological and sustainable materials used either in the new construction or in the rehabilitation of old buildings. In this context, a comparative study was based on the valorisation of marble and ceramic waste as sand in sand concrete made from straw fibres. To carry out this study, we introduced these wastes at substitution rates of 10% and 20%, separated and mixed, and studied the development of the properties of these concretes (density, workability, air content, compressive strength and bending tensile strength) and their behaviour with respect to durability (capillary and immersion absorption and chloride penetration). The study shows that the recovery of this waste as sand in sand concrete based on straw fibres gives satisfactory results. The chemical resistance, thermal conductivity and microstructure are under study, the results of which will be the subject of another publication.
