When making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mixture. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need.
The shear strength of cohesionless soils may be expressed by –. r = σ' tan ɸ … (13.36) Factors affecting the shear strength of sands are the following: 1. Particle Size: Gravels have higher friction angle than that of sands, which, …

Very fine soils (clays and silts) typically have lower capacities than coarse granular soils (sands and gravels). However, some clays or silts have higher bearing capacity than the values in the code tables. If you have a soil test done, you could discover that you have a denser clay with a much higher bearing strength.
Procedure - The green compressive strength of green sand is the maximum compressive stress that a mixture is capable of sustaining when prepared, rammed and broken under standard conditions. The rammed cylindrical specimen (2 in. diameter and 2 in. long) is formed by placing a weighed amount of sand in a tube and ramming the …
Inclusion of 50-60% CS is found to provide maximum density and compressive strength, and beyond 60% CS content, strength begins to drop. CSEBs made with cement ≥6% with proper amount of sand ...

The EN specifications list the 0.2% proof strength values, Rp0.2, at temperatures above the room temperature, up to the temperature where time dependent properties govern. Verification of the 0.2% proof strength, 1.0% proof strength, and/or tensile strength at elevated temperature for austenitic steels is subject to agreement.

These results show that sand of the same predominant mineral composition (e.g., > 98 % silica), of the same grain size distribution, and from the same geological formation but from different quarries within the formation do not necessarily respond in the same manner to biocementation. Hence, standard sands for mechanical geotechnical …
The grain size for each group corresponds to 0.85–1, 1–1.18, 1.18–1.45, 1.45–1.66 and 1.66–2 (mm) respectively. The image recognition technology allows processing a large number of grains each time, about 400 grains. The high-quality photos of sand grains on shadowless LED flat lamp were taken by 24.3-million pixel cameras.
