“…It can be also observed that both the strength and the fracture energy of masonry samples in the two examined directions are comparable to those of the homogeneous material, as reported in the technical literature [5,35,37,38]. …”

“…The first ones, characterized by a 40 mm square basis and 80 mm height, provided indeed an average uniaxial compressive strength approximately equal to f AAC = 2.8 MPa, while for 40 mm side cubes a value of f AAC,cube = 3.1 MPa was found. These values were almost coincident with those provided from standard tests previously carried out on the adopted raw material (see [35] for further details), as well as with those available in the technical literature for a material with similar density and moisture content [5,6]. Anyway, it should be kept in mind that AAC compressive strength depends on the geometry and dimensions of tested blocks.…”

“…Therefore, it offers excellent sound and thermal insulation properties [2,3], which have led in the past decades to an increasing use of this material for non-structural applications, especially cladding and infill panels. Anyway, AAC is also characterized by a good mechanical strength and fire-resistance (due to its incombustible nature) that make it suitable for the realization of masonry bearing walls of low-to-medium rise buildings, even in seismic zones [3][4][5][6][7][8][9][10]. Compared with conventional concrete (including concrete made with lightweight aggregates), AAC has typically a lower density (which in turn reduces the seismic inertial forces acting on the structure), ranging from one-sixth to one-third, and by a lower compressive strength, which is almost reduced in the same ratio.…”

“…According to standard EN 680 5 , reference drying shrinkage should be preferably specified. There is practical evidence that the reference drying shrinkage is relatively low as compared to the total drying shrinkage and it could seem that it is safe to rely on in terms of scratch resistance of masonry.…”

Autoclaved aerated concrete (AAC) products are characterized by relatively favorable compressive strength at low density and high thermal insulation and thus significantly affect the saving of the energy needed for heating buildings, ensuring them a healthy microclimate. The modern technologies of manufacturing AAC, characteristic of AAC products and effects relating with them to show that above production of AAC blocs and applying them to building industry meets the requirements of sustainable development. Over the years, the standardization of AAC was developing. There is currently one "EN 771-4 10 Specification for masonry units -Part 4. Autoclaved aerated concrete masonry units." It would be necessary to consider additional research to point explore multipurpose use AAC in different European Union countries. The article presents functional properties of AAC, which are important from the construction process and users.

“…Foaming agent is used to develop porous in the geopolymer pasta. [4] Lightweight concrete properties into concrete mixture was hardly influenced by foaming agent doses. In previous studies, added foaming agent at dosage of 0%, 0.3%, 0.6%, and 0.9% into concrete mixture experienced to give good properties of lightweight concrete.…”

Density and morphology studies on bottom ash and fly ash geopolymer brick AIP Conference Proceedings 1835, 020047 (2017) Abstract. The aims of this study is to obtain optimal doses of foaming agent on lightweight geopolymer concrete using fly Ash (FA) and metakaolin (MK) as raw materials. Several test was conducted in order to obtained characteristics of geopolymer lightweight concrete using foaming agent with different doses. The levels of foaming agent used was 0%, 0.3%, 0.6% and 0.9% from the binder weight. Level of metakolin content of 25% by precursor mass were applied in this research. In addition, activator solution with the ratio of Na2SiO3 / NaOH of 2 and Concentration of NaOH of 10 Molar were performed in this research. Doses of foaming agent of 0%, 0.3%, 0.6% and 0.9% by weight of the binder was used. Based on test results obtained, the best mechanical and physical properties of lightweight concrete was owned by speciment with doses of foam 0%. The recommended foam dosage is 0.3% due to its fair enough mechanical and physical properties of lightweight geopolymer concrete produced.
