Process for constructing compact longitudinal concrete

A process for constructing a compact longitudinal first concrete member, the process using four consecutive steps of providing and using a partially suspended horizontal hybrid sling with an under loop bearing support, the hybrid sling acting as a mold confining fluid concrete, the hybrid sling having an open throat at its upper end attached to an open rim frame, the sling loop having a long central body portion between two end closures, the central body portion with its two attached end closures making a closed ended trough-like mold container used in constructing the first concrete member, the first step consists in providing a pliable sheet, the sheet being used in making the central body portion, the second step consists in providing rim support equipment for partially suspending the hybrid sling, the support equipment requiring a long narrow rectangular horizontal open rim frame, having two spaced apart parallel side rails terminating at short end cross rails while the rim frame is supported at a predetermined height above said under loop bearing support, by rim frame support equipment resting upon an equipment base, the support equipment consisting of a plurality of inverted "U" shaped supports spaced apart one from another along a common alignment centerline, each "U" support having two uprights spaced apart one from another at equal distances transverse to said alignment centerline, the uprights having upper ends interconnected by a cross-tie beam while having lower ends resting on said equipment base, the third step comprises assembling and attaching an end closure to each end of the sling portion, to create a closed end trough-like compartment having an upper rectangular pliable rim edge, the third step further consists in placing the trough-like compartment beneath the rim frame and attaching the rectangular pliable rim edge to the frame, while the hybrid sling central body portion hangs downward such that the bottom of its loop rests upon the under loop bearing support and where at the bottom of the loop is spread out evenly without wrinkles and creases, the fourth step consists of ingressing a first pour of fluid concrete through the open rim frame into the undistended closed ended hybrid sling whereby the thus confined fluid concrete provides fluid pressures distending the hybrid sling to produce uniform cross-sectional configurations along the length of the now distended hybrid sling, the fluid concrete upon gaining a set produces a long compact concrete member having the same cross-sectional configurations along its length.
