“…A concrete is manufactured based on previous formulations [21][22][23][24], so we applied an optimization based on the interpretations of the previous results, in this investigation. The goal was to achieve a concrete mix with satisfactory workability and exceptionally high strength, particularly in terms of compression resistance.…”

Construction development is inevitable, while despite its advantages and its benefits, it may lead to several problems related to landfill and its storage, referring to the high volumes of concrete waste currently generated annually, almost 2.0 ton/per capita according to Eurostat. In Algeria, the government has integrated waste management strategy [3] provision to recovering 60 % of construction waste by 2035, which can translate to an urgent need to find innovative ways to recycle concrete waste. One is using those wastes to produce aggregates; however, around 20 % of those aggregates represent fines, wich can lead to several issues if not considered in the concrete mixture. This work is an investigation that allows for using this fine fraction as partial replacement of cement. The result confirms the feasibility of using this material efficiently by applying an optimization process, ensuring an optimal cement replacement percentage.

“…Considering that there are few theoretical bases for UHPC design, further experimental studies are essential for achieving UHPC [ 6 ]. A few mix design methods have been investigated to simplify the UHPC design workload [ 7 , 8 , 9 , 10 ]. Four types of mix design methods have been proposed in the literature, which are based on rheological properties, statistical designs, neural network models, and close packing models [ 11 , 12 , 13 , 14 , 15 ].…”

The mix design of UHPC has always been based on a large number of experiments; in order to reduce the number of repeated experiments, in this study, silica fume (SF), fly ash (FA), and limestone powder (LP) were used as the raw materials to conduct 15 groups of experiments to determine the particle size distribution (PSD) properties of UHPC. A model of multi-component hydration based on the SF, FA, and LP pozzolanic reactions was devised to quantify the rate and total heat release during the hydration process. Additionally, a microscopic pore development model, which was based on the accumulation of hydration products, was established to measure the effect of these products on the particle-packing properties. Utilizing this model, a UHPC strength prediction technique was formulated to precisely forecast the compressive strength based on a restricted experimental data set. The applicability of this prediction method was verified using 15 sets of existing experimental data along with the data collected from 4 research articles. The results show that the prediction method can predict the strength values of different mix proportions with an accuracy rate of over 80%.
