Interpret the grading curve for shotcrete - Putzmeister

Learn how to interpret the grading curve to obtain a shotcrete mixture with an adequate aggregate amount. It is easier than you think! which means that 1,2 % of the aggregate particles have a size between 8 and 16 mm. The particles between 4 and 8 mm represent 38,2 % of the total of the aggregate, those between 2 and 4 mm represent 10,6 %

Improve Your Shotcrete: Use Coarse Aggregates!

the coarse aggregate size should be larger than 1/4 in. (6.3 mm). As a guideline, it is believed the best results are obtained with Gradation #2, with a maximum aggregate size of 3/8 in. (10 mm), because this is what will promote an in-place composition as close as possible to that of cast-in-place concrete.2-4 To ensure improved properties

Coarse Aggregate Fine aggregate ratio in Shotcrete mix

The main parameters affecting the aggregate packing density are the shape and combined particle size distribution of the aggregates used in the mix. Once the aggregate supply has been selected, the only parameter that the mix designer can manipulate is the fine/coarse aggregates ratio.

What is the size of coarse aggregate used in concrete? - Quora

Mar 02, 2018  When the size of aggregate is greater than 4.75 mm ( say 5 mm) it is called coarse aggregate. Graded aggregates are used for better particle packing. The larger the size of aggregate lesser the cement required for same strength up to certain grade

Research on shotcrete in mine using non-activated waste

When the dry-mix shotcrete is specified, a mixture of pre-dampened aggregates and cement is conveyed by a hose to a nozzle where water is added and then projected at high velocity onto the surface (Serv, 2007). The coarse aggregates used in shotcrete is required to be smaller than 15 mm when wet-spraying technology is applied.
