			'''These are my notes I took from watching his video on lime stabilization in 10/2018.''' [[User:Aidan Williamson\|Aidan Williamson]] ([[User talk:Aidan Williamson\|talk]]) 20:58, 12 July 2019 (UTC)

			NRCS local office
			Conservation District


			ph lime 12.4 is what we want

			One sample: (% by weight)
			5% ph 11.5
			6 11.8 (max out)
			9 11.8 keep going until you make sure you can't go higher

			Use a ph meter. Calibrated with a calibration tube
			25 gram sample
			variable lime percentages
			use 150mm bottle
			fill to 150mm with distilled water
			Check the pH of the distilled water - should be 7.0
			soil should be sieved. maybe
			(3/8" sieve for block production)

			The soil needs to be a high concentration of clay to use lime


			sampling method is site specific.
			James Hallock does 2-3
			best method is a profile hole. walk down in and see the layers
			obviously, get below the top soil


			Callibrate mixer in field by filling a bucket and converting weight to volume measurements
			The mixer is a double hopper machine. Soil in one, sand and stabilizer in another.
			Belt feed additives to auger chamber

			Curing time: 28 days is standard for lime and cement
			Cement is faster to use. Can be a rock in 10 days
			Lime stabilized sits for 28 days in a cool, covered place. Can't really control the temperature in reality.
			the slower they cure, the better
			Lime reacts to electic charge of clay.

			Colorado: 14" thick wall with 2" insulation on the outside for cheap shit




			Moisture added right at the end of mixing
			about 10% moisture
			ball it up - if you poke it with your finger it should fall apart


			Homogeneity of mix is established before production (duh)

			Test results help onboard engineers and architects.
			Ongoing test results - maybe 1 block in 1000
			You can make rooves out of the blocks

			Mortar: same as blocks with more sand and more stabilizer. mortar isn't compressed so it needs more stabilization. Milkshake consistency. Want to pour it. It's not like fired bricks. Airplane the joints to lay faster.

			Example: incease sand by about 50%, double the stabilizer amount

			Testing Mortar: Glue 3 blocks together. Cure for 2 weeks. Support both end blocks. center block is unsupported. add weight until joint fails.

			Building: story pulls
			3x3x3/16"x10' angle for the corners. square the story pull so course is level and plum. takes time to put up story pull but it's really useful.
