What does the s mean in concrete?
The 's' stands for 'slump'. How wet the concrete is. S1 is prity dry (for laying kerb stones). S2 is wet (for foundations). S3 is very wet (pump mixes). Regards Colin, a Tarmac concrete batcher. 2nd Answer: It should be noted that the concrete should be as dry as practical to enable it to attain the highest potential strength. Concrete should never be so wet that it flows into the forms like tomato soup. In foundations in particular, you want the best strength you can get, as the entire structure will apply force to them. It should take some handwork with shovels to "ker-chunk" the concrete into the nooks and crannies of the forms. For vertical forms, using a 'stinger' or vibratory device is preferred to settle the concrete into all the nooks and crannies. A 4" slump is about as wet as you want the concrete mix to be. If you pick up a handful (with gloves) of fresh concrete and mold it into a fat cigar shape, it should hold that shape when you open your fingers. When the concrete mix comes down the chute of the delivery truck, it should stand up on the ground in a little hill, but with some spreading out, too. For all but the dry structural concretes, you can increase the fresh concrete's slump (wetter) by adding 1 gallon of water for each cubic yard of concrete for each additional inch of slump desired.

What is the definition and specifications of fair-faced concrete?
Fair faced concrete is one which after removal of form work is not required to have any further finishes on it like plastering, etc. Since concrete surface is intended to remain visible all relevant specifications of the concrete surface need to be given in the Tender. Broadly speaking these specification besides giving compressive strength, etc. of the concrete should also be dealing with desired appearance of the concrete. As in all works, they should also specify tolerance limits of defects or blemishes for fair faced concrete. Generally blemishes associated with Fair faced concrete are Blowholes, Steps, Fins, Colour variation, etc. For details and better understanding you may refer to 'Guide to Off form concrete finishes' published by Cement Concrete and Aggregates Australia' Though in India we do not follow it I found it interesting and quite in detail.

How do you get a bitumen stain out of a shirt?
Bitumen or tar is an organic substance that repels water. The stain should therefore first be softened in an organic solvent (petrol or gasoline will do this but this should be done out of doors and away from any flame source) and as much of the bitumen as possible removed. Once this is done a hand cleaning substance (such as 'swarfiga') can be applied and worked in to the stain then the area rinsed in warm water. After this a good wash in a washing machine with normal household detergent should bring the stain out. Alternatively you could take the shirt to a reputable dry cleaners and ask them to remove the stain.
