Application of restaurant waste lipids (RWL) as a binder component in metal injection moulding
… Restaurant Waste Lipids (RWL) is introduced as binder component in metal injection moulding since it’s contains rich amounts of free fatty acids which is suitable as secondary binder components. Different binder formulation of RWL and Polypropylene (PP) were prepared as the binders and the …

Effect of Concentration of Sphagnum Peat Moss on Strength of Binder-Treated Soil
… from commercially available components. Soil-binder mixture specimens with different values of organic matter content, OM, binder content, water-to-binder ratio, and curing time were tested for unconfined compressive strength (UCS). Least-squares regression was used to fit a predictive …

Hybrid optimisation electromagnetic interference shielding effectiveness:mechanical and physical performance of plaster mortar containing palm oil fuel ash using taguchi grey and taguchi-flower pollination algorithm methods
… POFA admixture percentage, topcoat powder /binder ratio (TP/B), water/binder ratio (W/B), latex agent content (LA), the particle size of POFA and curing condition are used to control the nine responses. Pre-experiment data is optimized based on Taguchi-grey and Flower Pollination Algorithm …

Engineering properties of ring shaped polytheylene terephthalate (RPET) fiber self-compacting concrete
… This study mainly determines the optimum water– binder ratio and fiber content of RPET fiber concrete (FC) through self-compacting, as well as through compressive, tensile, and toughness strength tests. A water–binder ratio of 0.55 and working ranges from 0.25% to 1% of fiber content are …

Numerical Modeling of UHPC using a Concrete Damage Plasticity Model
… are achieved through the use of a low water-to-binder ratio, optimized matrix packing density, and the addition of fibers. Although UHPC has the potential to be used in innovative and economic structural applications and is well-suited for efficient structural design against extreme loads, its …

Macro and nanocreep of self-consolidating concrete
… SCC was compared with NVC that has similar water/binder ratio, volume of cement paste and ultimate compressive strength. Moreover, creep of SCC was compared to creep predicted using the ACI-209 and CEB-FIB MC90-99 models. Nanoscale creep experiments were performed using nanoindentation. …

Composite propellant combustion with low aluminum agglomeration
Aluminum behavior—accumulation, agglomeration and ignition—is studied in a unique, wide-distribution, ammonium perchlorate/hydroxyl-terminated polybutadiene (AP/HTPB) propellant formulation that results in low Al agglomeration, even at low pressures (1-30 atm). Variations in formulation—such as …

Development of low-clinker concrete: partial replacement of cement with calcined clay and limestone, based on selected African raw materials
… An attractive option is to produce LC3 binders, which consist of ground limestone, calcined kaolinite clay, and cement. In this study, the suitability of kaolinite clays for use in LC3 binders from selected deposits in South Africa and Tanzania was assessed. Four samples of clays were …

An international perspective on performance-based specifications for concrete durability, with a suggested framework for implementation
… specifications often lead to the early deterioration of RC structures, escalating global maintenance costs. Prescriptive durability specifications for reinforced concrete (RC) often include mix design parameters such as minimum cement content and maximum water/binder ratio, which are intended …

Evaluation of Nevada's Warm Mix Asphalt Mixtures with Recycled Asphalt Pavements
… two different percentages of recycled asphalt binder ratios were used.Aggregates from Lone Mountain, North Tenaya, Spanish Springs and Lockwood were used with appropriate binders for the particular climate conditions in those areas. All the aggregates were lime-marinated, as per requirement of …

Bond Performance between Corroded Steel and Recycled Aggregate Concrete Incorporating Nano Silica
… the performance of concrete with different water/binder (w/b) ratios has been also studied, using 63 different mixtures produced with three different types of colloidal NS having various surface areas and particle sizes. The results showed that the performance of concrete is heavily influenced by …

The effectiveness of a percussion drill method for making concrete cube samples to assess the characteristics of precast zero-slump concrete
… method. The specific factory mix had a water-to-binder ratio of 0.25, a very stiff and dry mix. Therefore, the percussive action of a percussion drill was used for compaction to achieve a target density. The aim was to achieve a compressive strength of 30 MPa at 18 hours and 50 MPa at 28 days. …
