concrete materials estimator

This is a simple but very useful app for computing concrete i.e. cement ,sand and gravel proportion in most common concrete structure like columns, slabs, or similar structures of prism or cylinder shapes. This app outputs standard classes of concrete mix proportions (class AA, class A, class B, class C, and class D). Also in this version, allows the user to calculate the number of concrete hollow blocks (CHB) given the height and length of a structure, say a wall, and the area off openings like doors and windows. Along with it is the estimate of mortar fillers for block laying and cell, plaster finish, CHB reinforcement bars and tie wires. Conversion of units of measurements (inch, feet, and meter) is also included.

Future improvements will include estimate of reinforcements to concrete structures, roofing etc.
