Utilisation of phosphogypsum along with other additives in geo- engineering- A review <p>Various adverse effects and hydro-mechanical failures of soil are the dominant effects of global warming. At the same time, rapid industrial development has produced several by-products on a large scale. The reuse of industrial residues in different engineering fields without compromising the technical characteristics is propitious from the engineering, environmental, ecological and economic points of view. Phosphogypsum (PG) can be used as an alternative civil engineering material as it is rich in calcium sulphate, although it contains some radioactive molecules. Researchers are continuing to investigate the utilisation of PG by mixing it with other traditional materials to convert into alternative materials when the radioactive minerals are within the permissible limits. However, the contamination effect can be reduced by treating with citric acid. This review paper presents details of the increase in strength parameters and permeability of PG when combined with other wastes materials used in different geotechnical fields.</p> B. Anamika G.

Nevertheless, multiple resources in the literature have reported reductions in its mechanical properties directly proportional to the rubber content. Over the last few years, various mathematical models have been proposed to estimate rubberized concrete properties using artificial intelligence, machine learning, and fuzzy logic-based methods. However, these models are relatively complicated and require higher computation efforts than multivariable regression ones when it comes to the daily usage of practicing engineers. Additionally, most of the study has mainly focused on the compressive strength of rubberized concrete and rarely went into more details considering other properties and sample sizes. Therefore, this study focuses on developing simple yet accurate rubberized concrete multivariable regression models that can be generalized for various mixtures of rubberized concrete considering different sample sizes.</p> A.

In this paper, experiments were designed based on the Taguchi method and on the freezing resistance and pore structure characteristics of CSG after adding admixtures. After 20 freeze-thaw cycles, the results showed that both the compressive strength and dynamic elastic modulus of CSG decreased. The area occupancy of more harmful pores (&gt;200 nm) in the NMR test increased, and the fractal dimension of the pore structure in the SEM images also increased. Based on the above indicators, it was concluded that L9 (sodium dodecyl sulfate, graphene oxide, nanosilica powder, and water-reducing agent) has the best freezing resistance. Experiments were conducted on L9 to verify that L9 can significantly improve the freezing resistance of CSG materials under different water-binder ratios, sand ratios, and cement dosages.</p> L.

Many flexural fatigue test results of plain normal-weight concrete are available in the literature and almost every set of test results provides different fatigue equations. It is necessary, though, to have a common fatigue equation to predict the design fatigue life of concrete structures under flexural load with reasonable accuracy. Therefore, a database of flexural fatigue test results was created for concrete with strengths ranging from 25 to 65 MPa; this database was used to derive new fatigue equations (Wöhler fatigue equation and&nbsp;<em>S-N</em>&nbsp;power relationship) for predicting the flexural fatigue life of normal-weight concrete. The concept of equivalent fatigue life was introduced to obtain a fatigue equation using the same stress ratio. A probabilistic analysis was also carried out to develop flexural fatigue equations that incorporate failure probabilities.</p> K.M.A. Sohel M.H.S. Al-Hinai A. Alnuaimi M. Al-Shahri S.

However, because of this increasing, a large volume of wastes is generated. One of them is a lime mud, resulting from the Kraft chemical pulping production process. Thus, the aim of this study was to evaluate the replacement of hydrated lime by lime mud on laying and coating mortars production, in order to verify its feasibility for possible application in civil construction industry. The 100% hydrated lime replacement mortar reached a 28-day compressive strength of 5.84 MPa. Finally, the results obtained in the experimental program showed that the 100% hydrated lime replacement mortar by lime mud meets the normative requirements for multiple-use mortars.</p> H.

The possibility of calcined red mud cement pastes with and without colloidal nano-silica (CNS) over Ordinary Portland Cement paste (OPC) at three W/B ratios (0.3, 0.4, 0.5) is evaluated. The optimum percentage of cement replacement by red mud (15%) was selected from compressive strength values of different cement replacements (5%, 10%, 15%, and 20%). Colloidal nano-silica (CNS) was added at 0.5%, 1%, 1.5%, and 2 % to the selected red mud cement paste. Water absorption, sorptivity, resistance to sulfate attack, and resistance to acid attack tests were conducted for optimum red mud cement paste with and without CNS. The experimental results are explained based on tortuosity with empirical formulas and mathematical models of pore network distribution. The tortuosity is directly proportional to the inter-connectivity of the pores. The mixes with 15% calcined red mud and 1.5% CNS replacement performed better strength and durability at all W/B ratios. The mix (R15NS1.5) with minimum tortuosity value results in the higher overall performance of the paste. The mixes with a 0.3 W/B ratio give high-performance cement paste compared to higher W/B ratios.</p> K. Athira T.

The treatments were applied in laboratory by capillary suction and their effectiveness and depth of penetration have been evaluated on the basis of the petrophysical characteristics of the stone (petrography, elemental physical properties, hydric properties and ultrasound propagation), before and after consolidation. Subsequently, in order to estimate the durability of the treatments, accelerated ageing tests (salt crystallisation, freeze-thaw and wet-dry) were carried out. According to the results, we can conclude that none of the treatments is suitable for the treatment of Novelda stone. However, we consider that with further in-depth study Tecnadis ZR-110 could offer good results.</p> A. Ripoll A. Rojo V. G.

Cork granulates were bonded with water-based epoxy and acrylic resins. The obtained panels were acoustically and mechanically tested. The results showed values of sound absorption coefficient close to 0.50 and acceptable flexural strength for their use as suspended ceiling tiles. Therefore, these bio-based panels could be used as an alternative product to the traditional materials used for noise control applications inside commercial spaces like closed entertainment areas.</p> R.
