Rule of thumb: add 1/4" to the thickness of your slab for your slab concrete budget.This assumes you have the job evenly graded to the right depth, and the grade is well compacted. Odd shapes: Transform odd shapes into rectangles and they are suddenly easy to figure.Figure driveway 14...
aAs a rule of thumb, only to give an idea on orders of magnitude, steel is protected at pH above ~11 but starts to corrode below ~10 depending on steel characteristics and local physico-chemical conditions when concrete becomes carbonated. Carbonation of concrete along with chloride ingress are...
Baroness Dean, the recently appointed chair of the Housing Corporation, put her foot in it last month. She told a housing conference that social landlords should ditch the worst estates, and concentrate investment on maintaining high quality in their best housing stock.Gosling, Paul...
Calculate the concrete material needed to pour a slab, patio, footing, column, or post-fill-project in cubic yards or pre-mix bags, and estimate the cost of materials. Project: Length: Width: Thickness: Monolithic Slab: Optionally enter the price per cubic yard Price: $ ...
This approach reduces the number of trainings and follows the rule-of-thumb that the optimal hidden layer sizes are between the size of the input and output layers [46]. The output layer provided the predicted values of k and fc. Note that all nodes in one layer are fully interconnected ...

Types of concrete grade and their strength as per European Standard (EC2)| Value of cube strength and cylinder strength are different for same mix. Value of cube strength is higher than cylinder strength. Using Thumb Rule, value of cube strength is is 1.25 times higher than cylinder strength....

The turbofan engines would struggle to handle the volume of air going into it. Structural loads and pressures on the air-frame are not equal, some parts of the plane can’t handle the stresses as some of the others. The rule of thumb is to go with the lowest known pressure statistics ...
The old rule of thumb was always 3 - 2 - 1. However, since the cement is the glue and you only want to do the patch once, why not add a little extra cement? Hydrated Lime - Secret Ingredient Do you recall the great book written by J.R.R. Tolkien -The Fellowship of the Ring?
