I just installed my new Speed Dawg knob and it is gorgeous! You guys do fantastic work! I ordered a custom knob to match my Grabber Orange Mustang and it was totally worth the wait! I am super happy! I even put your decal on my side window. Kudos to Speed Dawg!- Howard B., Fayetteville, NC.
A concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 3000 psi. Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens.
Concrete. This general purpose concrete, also concrete-aggregate (4:1 - sand/gravel aggregate: cement-mixing ratio w/ water) conversion tool is based on the concrete mass density of 2400 kg/m3 - 150 lbs/ft3 after curing. Unit mass per cubic centimeter, concrete has density 2.40g/cm3.
