· For normal use with a good subgrade and base material, using 4,000 PSI concrete reinforced with rebar, an eight inch thick slab will hold a big machine up. We are currently working on a project to support a machine weighing 30,000 lbs that requires a slab 6 ft thick, 14 ft by 20 ft to support it, simply because the machine creates extremely high inertia loads.

Consistometer. (Credit: AMETEK Chandler Engineering). API thickening time is measured in Bearden Consistency Units (Bc), on a scale of 0–100 Bc. A freshly prepared slurry will start at less than 30 Bc, and 100 Bc indicates the end of the test. Fig. 5.9 is a typical chart that is reported as a thickening time test.
Rate analysis for concrete – calculate quantity and cost, hi guys in this article we know about rate analysis of concrete m15, M10 and m7.5. Rate analysis comprise of sum of material cost, labour cost, overhead expenses, contractor profit and cost of equipment or tools.
From the above calculation, we have already got the weights of individual ingredients in concrete. So, the weight of concrete produced with 1 Bag of cement (50 Kgs) =50 kg + 115 kg + 209 kg + 27.5 kg = 401.5 kg ~ 400 kgs Considering concrete density = 2400

Concrete strike anchors are medium to heavy-duty anchors for use in solid concrete base material. The hole that needs to be drilled in the concrete is equal to the diameter of the anchor. The concrete strike anchor can be visually inspected to assure proper installation – when the center pin is flush with the top of the anchor the strike anchor is set properly.
