The aim of this contribution is to study the composition of the kukersite oil shale SHC retorting ash remaining at Enefit280 shale oil plants, to evaluate its self-cementing properties when hydrated with plain water, and to assess the development of compressive strength
upon alkali activation for potential geopolymer type cement and mortar applications.
Steam curing reduces the compressive strength
compared to the other curing types (Aldea et al.
A minimum compressive strength
value of 40 pounds/inch2 is suggested (Howard 2015) so that the flowable fill would be stronger than the existing soil, and have enough strength to be tested.

& Mechanical Properties of Concrete by Adding Human Hairs and Polypropylene ", International Advanced Research Journal in Science, Engineering and Technology, 3: 5.
The cube compressive strength
of Portland cement and binary and ternary cement concretes at the ages of 1, 2, 3, 5, and 7 days are presented in Table 4.
According to  stated compressive strength
is one of the strength properties that are considered important in timber design.
ck]--characteristic compressive strength
of concrete in MPa.
52)] showed significantly lower compressive strength
as compared to MC1 [287.
With these data, Young's modulus, Poisson's ratio, and the compressive strength
can be easily calculated.
To estimate compressive strength
of concrete containing different supplementary cementing materials, Papadakis et al.
, water absorption and unit weight tests were performed over the test specimens.
Properties to be tested are compressive strength
, water absorption and porosity.
