| Calcium ions (Ca) play an important role in many biochemical processes, delaying senescence and controlling physiological disorders in fruits and vegetables. The objective of this experiment was to analyze the effect of increasing calcium concentrations in snap beans. Snap bean cultivar UEL 1 was sown in sand containing 80 mg L-1 of calcium supplemented with nutrient solution, plus calcium at different contents: 0, 75, 150 and 300 mg L-1. Ca was mainly recovered in the shoots, followed by roots and pods. Calcium concentrations in the pods were 130, 259, 349 and 515 mg 100 g-1dry matter on a dry weight basis, in relation to the enhancement of calcium contents in the nutrient solution, respectively. A negative relationship between nitrogen content in the... |

| This study looks at the effect of cement replacement with locust bean pod ash (LBPA) as a supplementary cementitious material on compressive strength of mortars. The fresh properties (workability, initial and final setting times), compressive strength at 7, 14, 21 and 28 days and microstructural analysis (SEM, EDS and XRD) were evaluated. LBPA were considered at replacement levels of 0, 10, 15, 20 and 30% of cement mass for preparation of the mortar samples. Workability of the cement mortars reduced as the content of LBPA increases while initial and final setting times increased in relation to increase in LBPA content in the matrix. An increase of about 79% in compressive strength at 7 days, 100% at 14 days, 147% at 21 days and 136% at 28 days were... |
