steel vs. concrete: which comes out on top. posted by ken brakefield. topics: concrete is a composite material consisting of cement, sand, gravel and water. it has a relatively high compressive strength, but lacks tensile strength. concrete must be reinforced with steel rebar to increase a structure's tensile capacity, ductility and
compressive strength vs duration for concrete (crushed stone) of 1:1.5:3. 1:1.5:3 compressive strength of concrete by stone chip with normal sand and stone powder is quite close for 3 days which is 4.62% increased value from normal sand to stone powdered concrete. for 7 days the compressive strength of sand concrete is 22.21 mpa whereas for stone
flagstone is a unique paving surface that adds a natural look to any patio or walkway. it can be laid on a dry bed of sand and gravel or it can be mortared to an existing concrete slab. there are also three options for filling the joints between flagstones. joints over a dry bed can be filled with sand or can be planted between with groundcover

· the proper type of sand needs to be used for the best results. polymeric sand is highly recommended because once it is applied to the joints, it reacts with misted water and creates a binding agent that helps solidify the sand and locks the pavers together. the best polymeric sand to use is a brand like surebond.
