Mixing Cement - Lime - Kiln Dried Sand

[Omar]

Hey guys, we are looking to redo the bits between the paving slabs as they have cracked and had weeds growing through them. We have chizzled the stuff out and want to refil. Now someone at Homebase suggested we use kiln dried on its own but surely it is too thin to use on its own? I thought to use this sand and cement and also use lime as it hardens the mixture up? Is this a good idea? If not can you reccomend what we can use? We are looking to fill up to 1/4 inch deep. I also need to know what ratio sand-cement-lime powder I can use to make this very tough so it does not crack anytime soon.
Thanks a lot for any advice it is greatly appreciated.
Omar
