Oct 23, 2013 · Instructions were lacking other than ratio to mix. At first it didn't seem to be working. I let it set half an hr and went back and am pleased with results for so little effort. It didn't say to rinse but I didn't want to take a chance on footprints, inside on the carpet, so rinsed it off plus didn't think it'd be good for the concrete.

Apr 18, 2012 · Since IRC apparently specifies a maximum allowable W/C ratio of 0.5 for concrete exposed to freeze/thaw, the minimum practical strength that would be delivered is 4000 psi concrete. Of course, since only the plant actually knows the water/cement ratio used, the only relevant data about the actual water/cement ratio comes by back calculating the ...

Aug 6, 2023 · A "fat" mix from the concrete company would be a 5000psi mix, or a 6 bag mix, just more Portland cement. A concrete truck weighs around 30,000 lbs empty, and it will kill a concrete driveway if they drive on it. It will leave ruts in the grass. So you would probably have to wheelbarrow it to the pour site.

Sep 18, 2024 · Hello, I am ready to pour concrete into a 24" X 24" form set on top of the brick chimney. I need help with selecting the correct pre-mixed concrete. My cap will be 3" thick at the outer edges and 4" near the flue. I am using mesh reinforcement. I short-listed Quikrete sand-topping mix. Product 1103 as it mentions chimney cap. But the data sheet ...

Type N mix ratio is 1:1:6 Type S mix is 2:1:9 The ratio I gave you is somewhere in between giving you adequate strength and adhesion.

Nov 6, 2022 · What lime mortar mix ratio do you suggest? How to avoid mortar stains on brick faces when repointing? Some background: On the mortar mixes The bricks are rather soft. The two-story house was built around 1870. They are certainly from the low heat era. So a lime mix is certainly in order.

Sep 6, 2020 · Or is a higher psi not necessarily stronger. Im just trying to create a final product that will resist cracking or excessive chipping away from either general use or purposeful dropping. I am also trying to keep price/lb. of the concrete down. On sale, an 80lb bag of Sakrete 5000 Plus Concrete Mix is $4.

Jul 7, 2010 · Like Jo suggested fine grout may be better for you. If you will be laying block it sounds like you will have a mortar mixer on site. Fine grout will be able to be mixed in a mortar mixer, coarse grout (with stone) has to be mixed in a concrete mixer (spinning drum style). 1 part portland cement to a maximum 3 parts sand is a good ratio.

Jul 8, 2006 · 1. Concrete can take anywhere from 15min to 24hrs to set it all depends on what concrete mix is used, weather conditions, and the size of the mold. After release additional drying can be done out of the molds, the cycle time can be reduced further by using only enough water in the mix as absolutely needed, or using a faster setting concrete mix 2.
