Additives and Fillers in Concrete

89
Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.

Retarders01:19

Retarders

61
Retarders are chemical admixtures designed to extend the setting time, which is especially useful when there is a delay in sequential concrete pours to prevent cold joints and to achieve a cohesive structure. Retarders, when used in appropriate amounts, can also enhance the architectural appearance of exposed aggregate finishes.
The function of retarders is to delay the setting of concrete, and this effect can be measured using a penetration test. The retardation process involves adding...

Accelerators01:17

Accelerators

70
Accelerators in concrete serve as admixtures to speed up the hardening process, enabling the concrete to achieve early strength faster. Although accelerators do not necessarily impact the time it takes concrete to set, they reduce this time in practice. A common accelerator is calcium chloride, which is particularly useful for hastening early strength development in cold weather or for rapid repair jobs that require quick heat generation after mixing.
The effectiveness of calcium chloride can...

Plasticizers01:31

Plasticizers

65
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Waterproofing and Anti-Bacterial Admixtures in Concrete01:22

Waterproofing and Anti-Bacterial Admixtures in Concrete

74
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.
Waterproofing admixtures render concrete hydrophobic,...

Summary
This summary is machine-generated.

Supplementing pasture-raised beef cattle with protein-energy supplements (PESs) increased dry matter intake and improved nitrogen utilization. However, additives like monensin sodium, functional oil, or active yeast did not further enhance nutritional parameters in this study.

Area of Science:

  • Animal Science
  • Ruminant Nutrition
  • Pasture Management

Background:

  • Pasture-based beef systems rely on forage and supplements for optimal production.
  • Supplementation and additives can enhance nutrient utilization and production efficiency in cattle.

Purpose of the Study:

  • To assess the impact of additives in protein-energy supplements (PESs) on intake, digestibility, and ruminal parameters of pasture-raised beef cattle.
  • To compare the effects of monensin sodium, functional oil, and active yeast within PESs.

Main Methods:

  • A 5x5 Latin square design with five male cattle grazing marandu palisadegrass.
  • Treatments included a mineral mixture (MM), PES, and PES with monensin sodium, functional oil, or active yeast.

Main Results:

  • PES significantly increased total dry matter intake (DMI), DMI as % body weight (%BW), crude protein intake, and digestible organic matter intake.
  • Additives did not alter nutrient intake or digestibility.
  • PES increased ruminal ammonia nitrogen, serum urea nitrogen, fecal nitrogen, retained nitrogen, microbial nitrogen synthesis, and microbial efficiency compared to MM.

Conclusions:

  • Protein-energy supplements enhance DMI and nitrogen metabolism in pasture-raised beef cattle.
  • Monensin sodium, functional oil, and active yeast, under the study's conditions, did not provide additional nutritional benefits beyond the PES itself.
