A one chunk paragraph contains a transition word, a topic sentence, a concrete detail, two commentary sentences, and a concluding sentence. It is no less than five sentences, however, can be much longer in length.
What is the hardest cement?
PFC is an ultra-high-strength concrete whose properties can be further enhanced by incorporating steel fibers. The way in which PFC is prepared leads to very few voids in the final material, which gives it its high strength — 400 MPa can be applied to PFC before it fails, compared with 20-30 MPa for standard concrete.
What is 6000 psi concrete used for?
For new concrete construction projects, concrete overlays and concrete repairs. Use to construct footings, sidewalks, slabs, steps and patios, setting deck posts, fence posts or poles.
Can I use cement on its own?
Cement is a fine binding powder that is never used alone but is a component of both concrete and mortar, as well as stucco, tile grout, and thin-set adhesive. Mortar is composed of cement, fine sands and lime; it is used as a binding material when building with brick, block, and stone.
What is a good concrete mix?
In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 parts sand to 4 parts aggregates. For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used.
What is the smoothest concrete mix?

What is the strongest concrete mix ratio?
Concrete is made from cement, sand, gravel and water. In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water.
How many bags of cement do I need for 1 cubic meter?
We have now cut down to 1/2 a cubic metre apparently. The consensus for 1/2 a cube seems to be, 1 tonne sand, 14 bags cement. This should give 3:1 BY VOLUME!
