Concrete Calculator Estimate Cement, Sand, Gravel ...
Our mixonsite concrete calculation is based on batching by volume (Large construction sites employ batching by weight which is more exact). You can also estimate the quantity of sand and gravel required by weight; Simply multiply the volumetric quantity of sand and gravel with 1400 kg/m 3 (bulk density of sand) and 1600 kg/m 3 (bulk density ...

The 100 Year Flood and Return Period Estimation of Rainfall
Return period estimation of rainfall of given intensity and duration can be done using hydrologic principles. Hydrology teaches us about the probability of a 100 year flood, or 50 year flood, or 200 year storm occurring in any given time period at a given location. A 100 year flood will occur on the average once every 100 years at any given location, so its probability of occurring in any ...

We recommend a 61/2 bag mix or 4,000 PSI concrete with a 68% air entrainment and low slump in the 34"range to avoid Spalling of the surface from the winter. Then depending on the weather conditions, one might add fibermesh and a retarder to help the workability of the concrete and avoid shrinkage cracks.
