The arched strut is an addition to the strut-and-tie (STM) tool kit. It models the combination of disturbed behavior in one direction with slender behavior in the perpendicular direction. Common applications for the arched strut are in the design of

Clause 10.15.3 of the 1995 ACI code (ACI 318-95) defines the effective strength of a high-strength concrete interior column with an intervening normal strength concrete slab. This provision is based on laboratory tests in which no load was applied to

A statistical model derived from a Box—Behnken design with three variables was used to evaluate the effect on the mechanical properties of concrete of the amount of a superabsorbent polymer/clay composite (SAPC) added, the grain size of the SAPC, a

Electrochemical techniques were used to study the inhibition effects of molybdate (MoO42−), MoO42− + nitrite (NO2− ), MoO42− + tolyltriazole (TTA, CH3C6H4N3H), and MoO42− + NO2− + TTA on t...

Rhizosphere bacteria may enhance plant uptake of Fe by producing siderophores that chelate sparingly soluble Fe3+ in calcareous soils. To evaluate the extent to which plants benefit from colonization of the roots by prolific siderophore-producing bac

Non‐crystalline or short‐range order Fe oxides (sometimes called amorphous Fe oxides) are of interest because of their surface area and high reactivity, and their influence on Fe availability in the soil. Eight non‐crystalline Fe(III) oxides we

Siderophores produced by rhizosphere bacteria may enhance plant growth by increasing the availability of Fe near the root or by inhibiting the colonization of roots by plant pathogens or other harmful bacteria. To examine the populations of sideropho
