“…The ratio of silica fume/cement used is 10% for a water/cement ratio equal to 41%, close to the optimal values of previous studies of cement composites [11,13,16]. The aims of this work are to measure the ba sic static mechanical properties of these composite materials (as a prior step before determining the dynamic ones), to understand how their microstructure (types of alumina particles and of matrix) influences their strength.…”

“…These studies concluded that within the investigated range of the water/cement ratio (0.25 1.17), the smal ler the amount of water the higher the strength of concrete with out an addition of silica fume. However, it is necessary to use a super plasticizer at least in the low water/cement ratio [11,12] to get constant workability of the concrete. Duval and Kadri [11] also show that the optimal super plasticizer dosage (for a constant workability) is minimum when the quantity of cement is nine times the quantity of silica fume.…”

a b s t r a c tInnovative particle reinforced materials made of alumina particles and cement based matrix were designed, manufactured and tested to evaluate the potential use of ceramic aggregates in concretes.These particle reinforced composites were tested in three point bending and uniaxial compression con ditions to determine the influence of the shape and size of the ceramic inclusions, and the addition of sil ica fume on the mechanical properties. A specific methodology combining post mortem observations with a statistical analysis of tensile failure stresses (average strength and Weibull modulus) was con ducted to deduce the origin of failure for each cement based composite (porosity or ceramic particles/ matrix decohesion). A remarkable correlation is observed between bending failure stress level and the average strength measured under uniaxial compression loading. As main conclusion, addition of alumina particles in a mortar appears to strengthen or to weaken the composite depending on whether silica fume is used in the cementitious matrix.

“…This also applies to the disposal of waste from such industries as production of phosphate mineral fertilizers, alcohol and dairy products. One of the effective ways to dispose of these wastes is to recycle them for production of building materials [6][7][8][9][10], in particular, aerated concrete products. The purpose of these studies is to develop compositions and a production technology for modified non-autoclaved aerated concrete based on recycled industrial waste.…”

Abstract. The purpose of these studies is to justify the feasibility of recycling different types of industrial waste instead of conventional expensive raw materials in production of environmentally friendly aerated concrete with required construction and operational properties. The impact of wastes from various industries on the environmental condition of affected areas, as well as the results of their environmental assessment were analyzed to determine whether these wastes could be used in production of high-performance building materials. The assessment of industrial wastes in aerated concrete production suggests that industrial wastes of hazard class IV can be recycled to produce aerated concrete. An environmentally friendly method for large-scale waste recycling, including a two-step environmentally sustainable mechanism, was developed. The basic quality indicators of the modified aerated concrete proved that the environmental safety could be enhanced by strengthening the structure, increasing its uniformity and improving thermal insulation properties. The modified non-autoclaved aerated concrete products with improved physical and operational properties were developed. They have the following properties: density -D700; class of concrete -В3.5; thermal transmittance coefficient -0.143 W/(m°С); frost resistance -F75.

“…Fly ash from large combustion plants had a positive effect on solidification properties of cement and concrete [8]. Using silica fume, which was used in production of silicon metal or ferrosilicon alloys, increased strength of concrete and reduced its permeability [9]. Silica fume also reduced water / cement ratio in cement and helped to obtain impermeable internal structure in concrete [10].…”

Abstract-Sustainable construction technologies, which are necessary for sustainable environment are important to minimize environmental impacts of urbanization and for the maximum efficiency of the structure. For this purpose, construction of sustainable/green buildings is a growing trend in Turkey and the world. Solid waste management at green buildings is one of the important parameters for sustainability of the building.In
