Guan et al [14] investigated the effect of stone powder content and sand type on the bonding properties of concrete filled square steel pipes respectively Excessive stone powder content had a negative effect on the bonding properties Lu et al [15] used cement mortar made by replacing some of the MS with granite powder The water absorption

— Due to the high water contents in samples at W/C = very low viscosity was observed for the grout The grout containing 20% and 30% stone powder showed higher workability than the criteria but grout with a 40% stone powder content was more viscous than the base grout As seen at all stone powder contents the UCS

It is found that the MB value of granite machine made sand remains unchanged with the increase of stone powder content in the range of 0% 15% and the limestone crushed stone machine made sand and limestone pebble machine made sand increase with the increase of stone powder content
In this paper we show the influence of stone powder content on the mechanical properties of concrete by experiments and numerical simulations In numerical simulation this paper proposed a method whereby the stone powder in the numerical simulation of concrete is considered by the mechanical performances of mortar with the stone powder The results

In the videos below there are two bottles of sand one half full of sand and half full of air and the second half full of sand and half full of water If to begin both bottles are rolled slowly on their sides on a horizontal table the sand in both bottles will move to form packings of the granules with flat horizontal surfaces
— It is thus feasible to produce concrete by using MS in the place of natural sand [2] [3] Considering that the stone powder in MS maybe affect the behaviors of concrete some researchers focused on the influence of stone powder content on the properties of concrete containing MS [6] [12] [13] [14] It is found that the stone powder
