“…Most tests were conducted to study how the addition of GGBFS improves the geotechnical properties of expansive soils. The CBR of GGBFS in this study was over 60% with the highest value equal to 93.1%, which corresponds to the CBR test results conducted on a GBFS-aggregate mix [22], where CBR was between 74.2% and 104.5%, as well as to test results on a blended calcium sulfate-GGBFS stabilization mix, where the CBR value was equal to 100% 6 days after stabilization.…”

The increasing demand for building materials in the road industry creates interest for a new source of high-quality aggregates. In order to conserve natural resources, more attention is focused on anthropogenic soils and industrial solid wastes. For the successful application of these types of soil, a series of geotechnical and environmental tests have to be conducted. A potential hazard in the reuse of wastes from thermal degradation in the construction industry, particularly in reinforced concrete (RC) construction, is the migration of heavy metals into the groundwater environment. In this article, a geotechnical assessment of blast furnace slag (BFS) properties is presented. We conducted a series of CBR, and oedometric tests to evaluate the feasibility of BFS application in earth construction. The oedometric test results show acceptable compression characteristics which are in the range of natural aggregates. The CBR shows that this material may be used as a pavement subbase. We also noticed the preconsolidation pressure phenomenon in both Proctor and vibro-compacted soil during the oedometric test. The compression index and recompression index value show that the compression characteristics are close to those of dense sand. Based on the results described in the article, blast furnace slag is a candidate for technological application and can become one of the elements of sustainable development by contributing to a reduction in the negative environmental impact of production and use of building materials.

Blended Palm Oil Fuel Ash (POFA) concrete has the potential for application in organic acid environments such as peat land. However, there is a need to improve resistance of blended POFA concrete using silica fume as a pozzolanic material. There are limited studies of the blended POFA admixed with silica for organic acid exposure. In this study, compressive strength, porosity, and sorptivity of blended POFA concrete admixed with silica such as silica fume has been investigated by exposing the samples in peat water. Portland Composite Cement (PCC) concrete with similar target strength was used as a control mix. The blended POFA concrete contained 0%, 20% and 40% POFA as a cement substitute. Micro silica or silica fume was added with concentrations of 10% in each mixture. Portland Composite Cement (PCC) with similar target strength was used as a control mix. The resistance of the POFA concrete specimens to organic acid attack were measured by compressive strength, porosity and sorptivity development at 7, 28 and 91 days. Compressive strength of control mix declined, while strength of PCC and PCC-POFA concrete containing silica fume increased at 91 days. Porosity and sorptivity of PCC and blended OFA concrete followed the same trend with the compressive strength. Thus, blended POFA concrete containing silica fume has better resistance in peat water than that of the control mix.
