Concretes based on alkaliactivated binders have attracted considerable attention as new alternative construction materials, which can substitute Portland Cement (OPC) in several applications. These binders are obtained through the chemical reaction between an alkaline activator and reactive aluminosilicate materials, also named precursors. Commonly used precursors are fly ash (FA), blast furnace slag (GBFS), and metakaolin. The present study evaluated properties such as compressive strength, rate of water absorption (sorptivity), and chloride permeability in two types of alkaliactivated concretes (AAC): FA/GBFS 80/20 and GBFS/OPC 80/20. OPC and GBFS/OPC* concretes without alkaliactivation were used as reference materials. The highest compressive strength was observed in the FA/GBFS concrete, which reported 26,1% greater strength compared to OPC concrete after 28 days of curing. The compressive strength of alkaliactivated FA/GBFS 80/20 and GBFS/OPC 80/20 was 61 MPa and 42 MPa at 360 days of curing, respectively. These AAC showed low permeability to the chloride ion and a reduced water absorption. It is concluded that these materials have suitable properties for various applications in the construction sector.

Alkali activated systems are materials formed by alkali-activation of latent hydraulic or pozzolanic materials. The outcome is a polymeric structure with properties comparable to materials based on cement.The principle of the experiment is to compare selected properties of alkali-activated materials based on blast furnace slag and using various types of activator (sodium water glass, potassium water glass, DESIL AL and sodium metasilicate) to binders based on white and Portland cements of the highest quality. The samples were left for one year in environments simulating the conditions in the interior and exterior. Selected physical-mechanical properties were evaluated and compared.

Ground Limestone

For concrete constructions built as underground spaces, basements or cellars, it is necessary for these constructions to be able to resist the influence of groundwater pressure that could disrupt the compactness of the entire construction by its action. For this reason, constructions of so-called white boxes are often used. White boxes are concrete constructions whose main capability is high water impermeability, exhibiting at the same time minimal volume changes. These properties could be accomplished by a series of several technological precautions, one of which is the composition of the concrete mixture itself. The aim of this paper is to evaluate the influence of finely ground limestone and the latent hydraulic addition of finely ground blast furnace slag on the properties of concrete composite such as water impermeability, water absorption, or volume changes. These properties are vital for the construction of white boxes. In this paper, the suitability of the mutual combination of active and internal additive will also be evaluated.

The characteristics of mortars made from ordinary Portland cement with various composition of ground granulated blast furnace slag (GGBS) were investigated in this research. Ground granulated blast furnace slag (GGBS) was chose as an alternative binder to partially replace high energy consuming Portland cement in concrete according to the composition of the slag itself. GGBS were blended with Portland cement from 20 to 80 weight percent. The samples were mechanically tested for water absorption and compressive strength after 7, 14 and 28 days. From research, the most suitable proportion is 60% OPC + 40% GGBS which gain the highest compressive strength and the lowest water absorption among OPC blended mortars. These mortars used water to hydrate and solidify with ratio water to binders 0.7 equally.

AbstractThe leachabilities of technetium and nitrate wastes immobilized in cement-based materials (i.e., grouts) have been investigated using ANS 16.1 test procedures. Factors found to affect the leachabilities include (1) grout mix ratio, (2) grout fluid density, (3) dry solid blend composition (including ground blast furnace slag), and (4) waste concentration.

The paper shows the results of an experimental tests campaign carried out on concretes with recycled aggregates added in substitution of sand. Sand, in fact, has been totally replaced once by blast-furnace slag and fly ashes, once by blast-furnace slag and microsilica. The aim is both to utilize industrial by-products and to reduce the use of artificial aggregates, which impose the opening of pits with high environmental damage. The results show that in the concretes so made the water absorption capacity has reduced and durability has improved. The test campaign and the results described in the present article are certainly useful and can be especially utilized for research on a larger scale in this field.
