view moreFor conventional concrete, the tensile strength is generally about 1/10 of the compressive strength, and the long-term tensile limit deformation is about 1.2~2.0 × 10 −4. Without considering the difference influence of temperature between laboratory and field, the mortar specimens will face the risk of failure in this paper .

view moreCompressive Strength Formula. Compressive strength formula for any material is the load applied at the point of failure to the cross-section area of the face on which load was applied. Compressive Strength = Load / Cross-sectional …
view moreThe results obtained using the three prediction methods given by Eq. – Eq. are plotted in Fig. 10. The UFC approach given by Eq. considered the effect of the compressive strength of the concrete and therefore serves as the purple region, in which the higher the compressive strength, the lower the BPL for the same explosive charge mass.
view moreA new deck system for moveable bridges was developed that makes use of ultra-high performance concrete (UHPC) reinforced with high strength steel (HSS) rebar to achieve the light weight and high strength requirements in moveable bridge applications. However, the typical deck strips of this deck system failed predominantly due to shear cracks in simply supported …

The prediction of geological polymerization parameters, such as DPT, DPH, GPT, and GPH, is very important for the mixing optimization of FA base polymer. In this study, machine learning models such as backpropagation neural network, support vector …
view moreSelf-consolidating concrete (SCC) has been used extensively in the construction industry because of its advanced characteristics of a highly flowable mixture and the ability to be consolidated under its own weight. One of the main challenges is the high content of OPC used in the production process. This research focuses on developing sustainable, high-strength self …
view moreThe mechanical properties of UHPC makes it a perfect material for applications where strength is a primary design criterion and concrete structural element sizes can be lowered to make them smaller, thinner, and more aesthetically acceptable, .It is commonly composed of Portland cement, fine aggregate, SF, a water-reducing additive with a high range of …
view moreResearchers found that the incorporation of 2 wt.% pre-soaked biochar as a filler in cement composites could improve cement hydration and enhance compressive strength (Gupta et al. 2018; Gupta et al. 2022). To the best of our knowledge, a large adoption (> 10 wt.%) of biochar in cement composites is still a challenging area because of the ...
