Concrete Basics: A Guide to Concrete Practice

I’ve been struggling to understand on if/why a concrete slab is necessary. I completely understand the need for footings and foundations – but slabs are not that clear. It’s somethinge eveyone seems to take for granted … but I am undecided on it.

Anyways …  I did come across this excellent free eBook generously published by Cement Concrete & Aggregates Australia – which seem to have many more freely available resources on their website. IF we do end up building with concrete foundations (yep – that’s an if!) we will probably hire a contractor for it – it’s one of those jobs where DIY doesn’t seem to have much point/value. Even so – this eBook is a must read because at least I know what to expect, to relate to engineering/design choices and to make sure things are getting done right on site.

I will probably be spending some time with their resources – I’ll let you know if I find anything interesting 🙂

Must Read on Hemp

I recently came across this excellent and free eBook on Hemp Lime Construction. It is published by a UK organization called “National Non-Food Crops Centre” – a name that was a huge lesson to me in it’s own right. In my mind “crops” was obviously associated with farming and food. I now know that there is an entire domain of farming for non-food crops. Two prominent example of non-food crops used in construction are Strawbales and Hemp. I am looking forward to learn what other surprises crops hold in store for me 🙂

Back to the book – it is a must read for anyone (home makers, architects, engineers, farmers,governments … ) interested in working with the magical substance that is hemp.

Here is a summary, quotes from the book itself, on the advantages of Hemp construction – just to give you a motivating flavor:

  • A means of achieving energy efficiency
  • A way of providing thermal mass
  • A breathable material which can help to create healthy buildings
  • Use of a material which is renewable and does little environmental damage
  • No pollution and no problems at end-of-life disposal
  • 95 Crop-based material which helps farmers and is a good use of land
  • Helps to facilitate healthier buildings
  • Offers the possibility of sequestering carbon into building fabric
  • Hemp lime has the ability to make an impact on the future of sustainable building by reversing the damaging effects of greenhouse gases. It is claimed that hemp lime can lock up approximately 110 kg of CO2 per m3 of wall.

I am sure I will be referencing this book often here on Bhudeva 🙂
