The best materials in the world cannot, by themselves guarantee a fine finished job. Skill in handling ingredients is the necessary step that turns the trick. The following suggestions might help. One, don't add water. Two, check your form work. Forms must be braced for the weight of the pour. Three, concrete is to be placed, not poured. Say no to extra water in the mix and place the concrete carefully making sure not to miss the corner pockets. Four, don't overwork the concrete. Overworking, especially a soupy mixture, causes separation. Five, use a drier mix on floors and pavements. Six, curing improves concrete. You can keep the concrete from drying out too fast by sprinkling repeatedly with water. Seven, correct cylinder making. And eight, observe cold weather suggestions. Nothing takes the place of heat and protection for protecting concrete.
