“…Figure-12 indicates a negative correlation between water absorption values and specific gravity. This is consistent with the outcomes of a previous work [25], indicating that aggregates of high specific gravity generally exhibit low water absorption. The relationships between AIV and ACV, LAAV and AIV, as well as ACV and LAAV show positive correlations, as shown in figures 13, 14 and 15.…”

Petrography and physicomechanical characteristics of Iyuku granite from southwestern Nigeria were investigated. Rock and aggregate samples were obtained from five different quarry sites for thin-sectioning and physical and mechanical tests. The rock slides were subjected to petrographic analysis, while the aggregates were tested for the parameters of specific gravity (S.G), water absorption, aggregate impact value (AIV), aggregate crushing value (ACV), Los Angeles abrasion value (LAAV), and flakiness and elongation indices in accordance with the British Standards (B.S), American Standards for Testing Materials (ASTM) and Federal Ministry of Works Standards (FMWS). The petrographic, physical, and mechanical characteristics were described by bar charts and linear graphs. The results revealed that the rocks are of medium to coarse interlocking grains, with no evidence of weathering influences, and quartz content ranging from 17% to 35%. The aggregates showed appreciable high S.G. values, very low water absorption values and low maximum permission limits for AIV, ACV and LAAV when compared with different standards. All the aggregates are adjudged to be generally strong and durable for road construction, but those with higher quartz contents are more preferable. Significant statistical correlations were established among both physical and mechanical tests conducted.

“…On average, mica content in gabbroid was small; thus, the small mica content together with other textural features had a positive influence on LA ˂ 24% and MD ˂ 11% (Johansson et al 2016). In the study by Amuda et al (2014), the high resistance to fragmentation of porphyritic granite was attributed to the low content of mica (biotite and muscovite).…”

Rock aggregates constitute the enormous volume of inert construction material used around the globe. The petrologic description as igneous, sedimentary, and metamorphic types establishes the intrinsic formation pattern of the parent rock. The engineering properties of these rocks vary due to the differences in the transformation process (e.g. hydrothermal deposits) and weathering effect. The two most common mechanical tests used to investigate the performance of aggregates are the Los Angeles (LA) and micro-Deval (MD) tests. This study reviewed the geological parameters (including mineralogy, grain and crystal size, grain shape, and porosity) and the relationship to Los Angeles and micro-Deval tests. It was found that high content of primary minerals in rocks (e.g. quartz and feldspar) is a significant parameter for performance evaluation. Traces of secondary and accessory minerals also affect the performance of rocks, although in many cases it is based on the percentage. Furthermore, some studies showed that the effect of mineralogic composition on mechanical strength is not sufficient to draw final conclusions of mechanical performance; therefore, the impact of other textural characteristics should be considered. The disposition of grain size and crystal size (e.g. as result of lithification) showed that rocks composed of fine-grain textural composition of ≤ 1 mm enhanced fragmentation and wear resistance than medium and coarse grained (≥ 1 mm). The effect of grain shape was based on convex and concave shapes and flat and elongated apexes of tested samples. The equidimensional form descriptor of rocks somehow improved resistance to impact from LA than highly flat and elongated particles. Lastly, the distribution of pore space investigated by means of the saturation method mostly showed moderate (R = 0.50) to strong (R = 0.90) and positive correlations to LA and MD tests.

“…The SG exhibits strong negative correlation with each of NMC and OMC (Table 3). Inverse relation between SG and OMC/NMC may be due to the fact that intact soil aggregates with low absorption rate has high specific gravity [82]. A moderate negative correlation exists between SS and SG, as well as SS and MDD (Table 3).…”

This study attempts to investigate the geotechnical properties of subsoils in an active Dumpsite (DS) within the basement complex area of Abeokuta, Nigeria with a view to assess its suitability as a foundation/filling material. Sixteen (16) composite soil samples were collected from four different parts of the DS at varied depths of 0.0 - 0.5, 0.5 - 1.0, 1.0 - 1.5, and 1.5 - 2.0 m. The soil properties considered are particle size distribution, Specific Gravity (SG), permeability, Shear Strength (SS), Maximum Dry Density (MDD), Optimum Moisture Content (OMC), Natural Moisture Content (NMC) and Atterberg limit (AL) indices. Results show that the assessed soil samples are sandy soils with less than 30% clay content. The ALs test revealed that analysed samples had low Plasticity index (PI) (0.20 - 11.96%), low values of Plastic Limit (PL) and Liquid Limit (LL) of (14.19 - 18.83% and 17.52 - 26.15%, respectively). The MDD values ranged from 1.07 to 1.76 g/cm3 while the NMC and OMC were <25% and <18%, respectively. The permeability coefficients ranged from 1.53 x 10−4 to 8.49 x 10−3 cm/s, indicating moderately permeable soil while the SS results (ranging from 3.4 to 12.5 KPa) indicate low cohesive capacity soils. The tested soils are mildly suitable for foundation/filling materials. Further study is needed to study the trend of alteration of soil properties with depth on dumpsite soil located on other geological formations.
