Concrete is measured by the cubic yard - measuring three feet by three feet by three feet, or 27 cubic feet. One cubic yard of normal concrete will weigh about 4,000 pounds.

Hydroxycitric acid (HCA), a derivative of citric acid, is found primarily in a small, sweet, purple fruit called the Malabar tamarind or, as it is most commonly called, Garcinia cambogia.hat Is the Scientific Evidence for Hydroxycitric Acid? It remains unclear whether HCA offers any weight-loss benefits. In an 8-week double-blind, placebo-controlled trial of 60 overweight individuals, use of HCA at a dose of 440 mg 3 times daily produced significant weight loss as compared to placebo.
Lactic acid is an organic compound with the formula CH3CH(OH)CO2H. In its solid state, it is white and water-soluble. In its liquid state, it is clear. It is produced both naturally and synthetically. With a hydroxyl group adjacent to the carboxyl group, lactic acid is classified as an alpha-hydroxy acid (AHA). In the form of its conjugate base called lactate, it plays a role in several biochemical processes. In solution, it can ionize a proton from the carboxyl group, producing the lactate ion CH. 3CH(OH)COâ. 2. Compared to acetic acid, its pKa is 1 unit less, meaning lactic acid deprotonates ten times more easily than acetic acid does.
