“…In general, the blended mixtures revealed dense, compacted and closed network structures. This structure justified the enhancement effect in the compressive strength of the blended mixtures cured under autoclave conditions (Kondo et al 1975;Wongkeo et al 2012). Figure 5 presents the EDX analysis of the M2-AC and M4-AC mixtures.…”

Investigating the microstructure of hardened cement mixtures with the aid of advanced technology will help the concrete industry to develop appropriate binders for durable building materials. In this paper, morphological, mineralogical and thermogravimetric analyses of autoclave-cured mixtures incorporating ground dune sand and ground granulated blast furnace slag as partial cementing materials were investigated. The microstructure analyses of hydrated products were conducted using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), differential thermal analysis (DTA), thermo-graphic analysis (TGA) and X-ray diffraction (XRD). The SEM and EDX results demonstrated the formation of thin plate-like calcium silicate hydrate plates and a compacted microstructure. The DTA and TGA analyses revealed that the calcium hydroxide generated from the hydration binder materials was consumed during the secondary pozzolanic reaction. Residual crystalline silica was observed from the XRD analysis of all of the blended mixtures, indicating the presence of excess silica. A good correlation was observed between the compressive strength of the blended mixtures and the CaO/SiO 2 ratio of the binder materials.

“…Thus, after 10 days, the total shrinkage is 1042 μm/m, 946 μm/m, 865 μm/m, 831 μm/m, 795 μm/m and 735 μm/m respectively for 0% T, 10% T, 15% T, 20% T, 25% T, 30% T. This result agrees with those in the literature [29,30] which showed that the addition of slow-acting pozzolanic additions reduces the shrinkage of mortars by increasing the size of the capillary pores, which would reduce the capillary pressure and therefore, the shrinkage. Yilmaz and Ucar [31] also reported similar results for Tuff (clinoptilolite) and attributed this to the reduction in water evaporation used for the formation of new hydrates.…”

This paper presents the feasibility of using locally available limestone Tuff in Burkina Faso as a partial replacement for CEM I artificial Portland cement. To this end, standard tests were carried out in the laboratory on mortars containing variable proportions of Tuff in partial substitution of CEM I cement. These include heat of hydration, setting time, total shrinkage, compressive strength, capillary absorption and resistance to acid attack. The experimental results obtained show that Tuff can be used as a natural pozzolan. It is also noted that the incorporation of Tuff into cement has virtually no influence on the transfer properties of mortars. However, at a rate above 15% partial substitution of CEM I, the mechanical strength of mortars is considerably reduced. This is probably linked to the finesse of the Tuff used. A finer shredding improved the mechanical activity index. However, we note a better resistance to acid attack (sulphuric acid that can come from acid rain) of mortars containing Tuff compared to mortar based on artificial Portland cement. All these results have shown that the Tuff used in this work can be a solution for reducing CO 2 emissions in cement production and also in reducing the price of cement in Burkina Faso.

This paper is devoted to research of possibility of utilization of granite dust. It is shown that the granite dust from the crushing screenings of "Shartashskiy stone-crushed stone quarry" can be recommended as a filler for the production of dry building mixes for flooring. With the introduction of dust in the amount of 20 % by weight of cement it is possible to obtain the mortar of the class not less B12.5.
