1. Radiation Balance and Partitioning of Latent and Sensible Heat Fluxes Over a Lime Orchard in Eastern Amazon
Abstract We investigate the balance of radiation and energy over a lime orchard in Eastern Amazon and how it relates to environmental conditions. We found that lime trees aged between 6 and 7 years old reflect 11.0% to 14.5% of incoming shortwave radiation, and the latent heat flux corresponds to 57.6% and 66.6% of the daily net radiation in the dry season (

2. Manufacturing and characterization of sustainable macroporous glass foams
Abstract This work produced glass foams from soda-lime glass bottles, bentonite, and alumina by the replica method. Compositions with different contents of bentonite (5, 10, 15, and 20 wt%) were prepared and heat-treated at 800 °C. In the alumina-added compositions, 50 wt% of the bentonite was replaced by the alumina. The influences of the content of benton

4. Soil stabilization with lime for erosion control in solar plants
Abstract The installation of solar parks requires extensive areas and results in soil erosion in many cases. One suitable solution is applying lime to improve soil characteristics, such as mechanical strength, stability, workability, durability, and internal and surface erosion resistance. This soil treatment is of particular importance when dealing with hyd

5. Evaluation of the use of silica-alumina refractory waste as a supplementary cementitious material
Abstract The use of supplementary cementitious materials (SMCs) is one of the three essential factors for the sustainability of the cement industry. To reduce CO2 emissions, several studies have introduced new methods for the utilization of industrial wastes such as the addition into cementitious materials. The objectives of this study were to chemically and

6. Evaluation of mortars produced with Baosteel slag short flow (BSSF) steel slag as fine aggregate
Abstract The objective was to evaluate the influence of Baosteel slag short flow (BSSF) steel slag, a byproduct of a Brazilian steel mill, as a fine aggregate on the properties of fresh state and on the compressive strength of mortars. The experimental work was to characterize the BSSF steel slag and to produce simple mortars (only cement) and mixed mortars

7. Analysis of carbonation and hydration of BOF steel slag for application as railway ballast
Abstract The reutilization of waste is a valuable alternative for the preservation of natural resources and the environment. In this sense, Basic Oxygen Furnace (BOF) steel slag is one of the most residues generated in steel the industry. It is estimated that for each ton of steel produced, about 150 kg of steel slag is generated in the BOF process. Generall

8. CONTRIBUTION OF ENZYMATIC METHOD FOR ANALYZING SUCROSE AND STARCH IN TRADITIONAL CHINESE LIME- AND EARTH-BASED MORTARS
Brown sugar and sticky rice were frequently used as organic additives in Chinese mortars. This study applied enzymatic spectrophotometric methods to identify sucrose and starch contents in traditional Chinese lime- and earth-based mortars. The focus was to understand and evaluate the qualitative detection capacity of enzymatic method in mortars, by first app
