TL;DR: In this article, the ash-portland cement mixture has been evaluated with respect to setting time, workability and compressive strength with a pozzolanic index value of 75.9%.
Abstract: Sawdust is a waste product from the timber industry. Research work carried out on the ash derived from the sawdust has confirmed its pozzolanic properties with a pozzolanic index value of 75.9%. This material compares favourably with fly ash and wastes from the oil palm industry. The only difference noticed is in the low content of Al 2 O 3 (4.09%) and Fe 2 O 3 (2.26%). Concrete mixes have been proportioned to have various percentages of cement replacement with sawdust ash (SDA) ranging from 0% to 30% by mass. Performance of the ash–portland cement mixture has been evaluated with respect to setting time, workability and compressive strength. From the results obtained, 10% replacement of cement with SDA shows good performance giving the desired workability and strength.

TL;DR: In this article, the use of two-stage activation process with semi-carbonization stage up to 200°C as first stage followed by an activation stage at a desired temperature, for production of activated carbon from carbonaceous precursors using phosphoric acid.
Abstract: The present work comprehensively addresses various experimental methods reported in the literature and substantiates the use of two-stage activation process with semi-carbonization stage up to 200°C as first stage followed by an activation stage at a desired temperature, for production of activated carbon from carbonaceous precursors using phosphoric acid. Efforts are made towards developing a high surface area activated carbon from rubber wood sawdust by a two-stage activation process with phosphoric acid as the activating agent. Experiments are conducted in a lab scale muffle furnace under static conditions in a self-generated atmosphere covering process parameters such as impregnation ratio, carbonization time and temperature. The precursor material with impregnation agent is exposed straightaway to semi-carbonization and activation temperature unlike following the specific temperature progression as reported in the literature. The process parameters are optimized based on product yield and iodine number. Semi-carbonization at 200°C for 15 min followed by activation at 500°C for 45 min with impregnation ratio of 1.5 yielded a product with iodine number 1096 which corresponds to a BET surface area of 1496 m 2 / g with the product yield of 35% and activation agent recovery of 90%.
