Experimental study of the effect of aggregate type on concrete strength
202151 The published results also show that granite aggregates produce concrete with higher strength than marble aggregates [12]. In addition, previous studies revealed that aggregate type has larger impact on the compressive strength of high-strength concretes than that of the normal-strength concretes [13].

20221024 The VA-70 asphalt, SBS-modified asphalt, five anti-stripping asphalts, limestone coarse aggregates, and granite coarse aggregates were subjected to surface free energy measurement. The surface free energy of the asphalts and aggregates and their components is presented in Table 7, Table 8, respectively. Their binding energy is
The particle-size distribution of concrete and mortar aggregates
2022722 The granite used as aggregate, already described in bibliography [], was collected in the quarry of Granialpa (Evora, Portugal, 38° 31′ 36.45′′ N–7° 59′ 49.93′′ O).The marine sand was collected at Sines beach (South-western Portugal) and the artificial glass microsphere have been acquired in an online shop.
Presentation of thermodynamic and dynamic modules
202266 The SFE results indicated that the granite aggregates had a greater polar component and limestone aggregates had a higher non-polar component which shows their higher moisture resistance. The adhesion free energy (AFE) results showed that the adhesion of base bitumen and limestone aggregate was higher, and using NHL improved
Influence of the Chemical Composition of Asphalt and the
202114 The influence of the chemical composition of asphalt, the aggregate lithology, and the morphological characteristics of the aggregate on the level of adhesion between the asphalt and the aggregate is investigated. A contactless three-dimensional (3D) white-light scanning technique is used to obtain point cloud data of the aggregate

Full article: Influence of aggregate absorption and diffusion
Left: Poorly performing granite aggregate–mastic bonds. The excellent (R 2 = 0.92) linear fit between adhesive strength and square root of moisture conditioning time suggests that a diffusion process controls mastic bond strength degradation in moisture-susceptible mixtures. Right: Good-performing greywacke aggregate–mastic bonds.

Surface free energy and moisture susceptibility
2016120 The values for the granite aggregate combinations are lower than limestone aggregate combinations. This is because of the silica (SiO 2) content present in aggregate which is an important factor to the adhesion properties. It has been generally observed that, limestone being alkaline aggregates has low silica content and provide
