CONCRETING Placing Concrete The main objective in concreting is to deposit the concrete as close as doable to its final position as quickly and with efficiency as you'll be able to, in order that segregation is avoided and it is totally compacted. Concrete is transported by a range of various ways starting from wheelbarrows, dumpers and ready-mix trucks to ships and pumps, and although it's clearly desirable to put the concrete directly into position this is often not always possible: as an example, it'll rarely be practical to discharge from a tipper truck or ready-mix truck directly into the highest point of a column or wall. Someone knowledgeable about the construction of formwork, ideally a tradesman, must always be standing by whenever the concrete is being placed. He ought to have a supply of appropriate materials like props, bolts etc. to handle dangerous situations. Grout loss is a sign that joints weren't tight or some movements have occurred throughout inserting. The vibrations transmitted to the formwork can loosen wedges and fixings, therefore, a detailed watch on all fastenings is critical to avoid loosening. Similarly, wedges ought to be frequently checked and tightened.
