MASON PRODUCTIVITY
continued from page 13
"The lightweight block had to be laid, the heavyweight block seem to lay themselves if you spread the right amount of mortar."
"I thought that it was taking just as long or longer to lay the lightweight block as it did the heavyweight units. I'm surprised at the results of the test."
"I furrowed the mortar sometimes and didn't furrow it at other times depending on the consistency of the mortar at the time and the unit to be laid. I was taught to not fool with the mortar, just pick it up and lay it down, that's why I like the mortar tubs over mortar boards, you don't have to roll the mortar to pick it up. If I don't have to furrow the mortar. I'm not going to. It just wastes time."
"I could pick up the 4"-24" long units with one hand, from a weight standpoint, but because of the length, I needed the other hand for balance."
"I'm not nearly as tired after laying these lightweight units as I was yesterday after the heavy ones. I was even able to keep my trowel in my hand some of the time. After you got used to these block, I think you could keep your trowel in your hand all the time and that's important. Every time you put your trowel down. you lose time. There is no way to keep your trowel in your hand while laying heavyweight block, either 16" or 24" long."
"I didn't knowingly slow down or speed up during the test. I tried to keep a steady pace. I might work faster on the job because I'm working against someone and don't want to be caught in the hole."
"I think the test was fair. You should cut these production figures at least in half due to job conditions, but all in all, it was a fair test."
