This document discusses the key ingredients and raw materials used in ordinary concrete, including the optimal water content. The main ingredients are cement, fine aggregate (sand), coarse aggregate (gravel), and water. Fine aggregate fills the spaces between coarse aggregate. Cement acts as the binding agent when mixed with water through hydration. The optimal water-cement ratio is important - too much water reduces strength, while too little reduces workability. Two common methods for calculating raw material quantities are discussed: 1) based on experimental dry-wet ratios and material unit weights; and 2) using yield and cement factor thumb rules.Mix proportioning dr. sdb.pptx

The document experimentally investigates the use of high early strength concrete for paver blocks. It summarizes that high early strength concrete can achieve structural strength within 24 hours, allowing blocks to be stacked sooner. The research aims to gain early strength and study properties using local waste materials like rice husk ash and calcium chloride as a cement replacement. Materials were tested and a mix design was developed. Fresh and hardened concrete was then tested, with compressive strength tests showing that concrete with a 15% calcium chloride accelerator achieved the highest strength at 7, 14, and 28 days. The conclusion is that the accelerator allows for higher early strength and durability compared to normal concrete.nanosilica for soil cement

This document discusses the use of nano-silica to improve the characteristics of soil cement used in pavement construction. It defines soil cement and its classifications. Higher cement content improves durability but can cause issues with fatigue and shrinkage. Shrinkage is caused by pores between 2.5-30nm in size. Pozzolanic additives like fly ash and silica fume can fill these pores and balance shrinkage and strength. Nano-silica, with particles 10-30nm in size, is proposed for further research to balance the competing design objectives in soil cement.Mix design by Indian standard method for M20

Solid control maintains desired drilling fluid properties by removing drilled solids. It is important for reducing costs, improving rate of penetration, and minimizing environmental impact. There are three main methods for solids control - dilution, displacement, and mechanical separation. Mechanical separation, using equipment like shale shakers and hydrocyclones, is the most efficient approach as it removes solids while minimizing additional fluid volumes. Proper solids control is key to economical and effective drilling operations.Mix Design of Concrete

Self-compacting concrete (SCC) is a highly fluid concrete that can flow and consolidate under its own weight without vibration. It was developed in Japan in the 1980s in response to a shortage of skilled labor. SCC mixtures have more powder and less coarse aggregate than conventional concrete, and include high-range water reducers and viscosity modifying agents. SCC allows for easier placement, improved surface finish, and greater design freedom.permeable concrete(sp).pptx

APM event hosted by the South Wales and West of England Network (SWWE Network)
Speaker: Aalok Sonawala
The SWWE Regional Network were very pleased to welcome Aalok Sonawala, Head of PMO, National Programmes, Rider Levett Bucknall on 26 February, to BAWA for our first face to face event of 2025. Aalok is a member of APMs Thames Valley Regional Network and also speaks to members of APMs PMO Interest Network, which aims to facilitate collaboration and learning, offer unbiased advice and guidance.
Tonight, Aalok planned to discuss the importance of a PMO within project-based organisations, the different types of PMO and their key elements, PMO governance and centres of excellence.
PMOs within an organisation can be centralised, hub and spoke with a central PMO with satellite PMOs globally, or embedded within projects. The appropriate structure will be determined by the specific business needs of the organisation. The PMO sits above PM delivery and the supply chain delivery teams.

Mix Design - SCC.pptx
- 1. Mix Design for Self Compacting Concrete
- 2. Mix Proportioning Principles as per IS 10262:2019 a) Lower coarse aggregate content, b) Increased paste content, c) Low water/powder ratio NOTE Powder refers to materials of particle size smaller than 0.125 mm. It includes this size fraction from cement, mineral admixtures and aggregate. Water/powder ratio shall be 0.85 to 1.10 by volume. d) Increased superplasticiser, and e) Use of a viscosity modifying admixture at times.
- 3. Typical Range of Mix Constituents as per IS 10262:2019 a) Powder Content (< 0.125 mm) in the range of 400 kg/m3 to 600 kg/m3, inclusive of suitable quantities of fine aggregate and mineral admixtures like fly ash in suitable proportions, may be used for flowability while ensuring compliance with engineering properties particularly shrinkage. Fine aggregate content, typically, 48 to 60% by mass of the total aggregate, balances the volume of the other constituents. b) Water content between 150 to 210 kg/m3.
- 4. Classification of SCC based on Fresh Prop. test Results Sl. No. Class/ Type Desired Range of Slump flow Applications 1 SF1 550 - 650 mm Unreinforced or Lightly reinforced concrete 2 SF2 660 - 750 mm Normal applications (for example, walls, columns) 3 SF3 760 - 850 mm Vertical applications in heavily reinforced structures, structures with complex shapes, or for filling under formwork a) Classification based on Slump Flow c) Classification based on V-Funnel Sl. No. Class/ Type Desired Range of V-Funnel Flow Time Applications 1 V1 (Less Viscous/ Better Flow) < 8 sec Good filling ability even with congested reinforcement. It is capable of self-leveling and has the best surface finish 2 V2 (Higher Viscosity/ Less Flow) 8 25 sec Improved segregation resistance. May Cause negative effects on surface finish and is sensitive to stoppages or delays between successive lifts Sl. No. Class/ Type Desired Range of Segregation ratio Applications 1 SR1 (More Segregation) 15-20% Thin slabs and for vertical applications with flow distance of less than 5 m and a confinement gap greater than 80mm 2 SR2 (Less Segregation) < 15% Vertical applications if the flow distance is more than 5 m with a confinement gap greater than 80mm b) Classification based on Segregation Resistance
- 5. Mix Design Steps as per IS 10262:2019 Step 1: Target Strength for Mix Proportioning Step 2: Selection of approximate Air Content based on maximum aggregate size Step 3: Selection of Water-Cementitious Materials Ratio (w/cm) Step 4: Selection of Water Content and Cement/Fly Ash (or other SCM) content. Step 5: Selection of admixture content Step 6: Selection of powder content and computation of fine aggregate content Step 7: Computation of Coarse aggregate content Step 8: Calculation of volume of powder content & Check for water/powder ratio by volume Step 9: Mix proportions for trial 1
