Carboline Engineering Sales Manager Jeremy Sukola joins Jack and Paul to discuss saturated surface dry SSDThe trio discusses the factors that make SSD crucial to a successful concrete resurfacing job.
Civil Engineering questions and answersThe porosity of a soil sample is 35 and the specific gravity of its particles is 2Calculate its void ratio dry density saturated density and submerged densityQuestion The porosity of a soil sample is 35 and the specific gravity of its particles is 2.
Determine the saturated bulk density of the soil in Example 2 assuming no volume changeIf the soil is saturated then S r 1Determine the void ratio of a saturated soil sample that has a mass of 178 g before drying and 139 g after drying in an ovenAssume the specific gravity of the soil solids to be 2.
Mass of oven dried aggregate 5216 g Mass of aggregates submerged in water 3295 Mass of SSD Saturated Surface Dry Aggregate 5227 g Find the aggregate bulk dry specific gravityReport your answer to two decimal placesDo not round till your final answer.
May 06 2022nbsp018332The procedure of the test was adopted from ASTM C127A sample of SDPMF was dried in an oven at 110 176C until a constant weight was obtained this weight was recorded as ovendried weight WoThe sample was then immersed in water for 18 hThe water on the SDPMF was wiped and the weight was recorded as saturated surface dry W SSD.
Nov 16 2020nbsp018332where P – apparent porosity M SSD – saturated surface dry mass g M D – dry mass g M SUB – submersed mass gEstimation of the degree of hydrationThe hydration degree was estimated by the apparent porosity of pastes obtained experimentally after drying the samples using solvent exchange and freezinglyophilization.
Ovendry OD All moisture is removed from the aggregate by heating in an oven at 105 C to constant weight overnight heating usually is sufficientAirdry AD All moisture removed from surface but internal pores partially full.
Ovendry OD all moisture removedAirdry AD surface moisture removed internal pores partially full Saturatedsurfacedry SSD surface moisture removed all internal pores fullHowever since the porosity of most rocks used in concrete is 1 to 2 the values of all specific gravities are approximately the same in the range of 2.
Paul This is truly when were talking about repairing cement products with cement productsThis is not what we look for if youre using epoxies or polyurias these arent the cases thenThis is truly for concrete repair products.
