I am researching the possibility for moulding high strength concrete sleepers at home. Dimensions would be approx 50 x 50 x 250mm. Ordinary concrete as used for paths etc isn't strong enough and takes too long to reach max strength. I fancy using fibre reinforcement. Is steel an option for such small sections? Stainless?
The actual loads are not great but cracks are most likely to develop around the fixings. These would be in the form of 4 plastic plugs placed towards the sleeper ends to receive rail screws. The idea is to position these plugs in the moulds and ram the wet concrete around them.
What would be a suitable mix and what additives should I try?
Many thanks in advance for any help.
