Very large sets of steps may require a concrete pad. The ultimate base, however, is a 6-inch-thick concrete pad on top of a properly prepared gravel pad. The gravel pad will stay compacted while allowing water to drain properly to guard against frost heaves. The concrete pad adds a solid, level area that makes setting the granite steps …
Teewhy2:. Is the mix same of you are using either gravel or granite with gravel u might need to reduce the sand content because the gravel itself comes with a lot of sand..... it is advised to reduce the sand, try a mix with 1 bag to see how it affects the final concrete and stick to what is thought best for the rest of the mix.

However, the combination and effect of different mineral admixtures on inhibiting ASR in granite-manufactured sand concrete and the in-depth understanding of the inhibition mechanism still need to be further …
material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete.
Granite dust is regarded as a valuable and easy-to-obtain alternative for customary, natural fine aggregate. However, granite dust can be employed in …
Highest compressive strength at all ages was noted with concrete made from quartzite aggregate followed by river gravel and then granite aggregate. Compressive strength models were proposed as a ...
affect concrete mechanical properties, namely aggregate type and temperature, the same proportions as limestone concrete were used for the granite and quartzite concretes. The amounts of materials used in the control mix to obtain 1 m3 of concrete are shown in Table 3 (which were identical in proportion for the other concretes).
As a contractor with extensive experience in excavation, gravel, and concrete work, I'm here to guide you through the importance of using a gravel base for your concrete projects. In this blog post, we'll explore the reasons why gravel is crucial for a strong, stable foundation, discuss the ideal thickness and type of gravel to use, and …
Abdullahi evaluated the effects of utilization of crushed quartzite, crushed granite and river gravel as coarse aggregate in concrete made with a water-to-cement ratio of 0.6. According to the report, the highest slump among the three mixtures was achieved with river gravel due to its smooth surfaces and rounded shapes which is …
Concrete made from 100 % granite and 100 % gravel served as controls while other constituents of the concrete were kept constant. Two different mix ratios of 1:2:4 and 1:3:6 were employed.
Nearly every community in nearly every industrialized or industrializing country is dependent on aggregate resources (sand, gravel, and stone) to build and maintain their infrastructure. Indeed, even agrarian communities depend on well-maintained transportation...
Since the aggregates make up the major part of the concrete mixture, their effect on concrete strength and permeability can be significant. For this reason, this paper presents the strength and permeability results of the concrete specimens, containing granite, andesite, silica, limestone, marble and tuff aggregates.
