What is the difference between cement and geo polymer?

User Avatar

Asked by Wiki User

Cement is a commonly used binding material in construction, made from limestone and clay that hardens when mixed with water. Geopolymer is a newer alternative material that uses industrial by-products like fly ash or slag, activated by an alkaline solution, to create a similar binding effect. Geo polymers tend to have lower carbon emissions and higher strength compared to traditional cement.

What is difference between Harp and fan designs of cable stayed bridge?

User Avatar

Asked by Wiki User

The harp and fan designs are two distinct cable arrangement patterns used in cable-stayed bridges. Each design has its own characteristics and advantages. Here's a concise comparison of the two:

Harp Design:

  1. Cable arrangement: Cables are arranged parallel to each other, forming a harp-like pattern.

  2. Anchoring: Cables are attached to the tower at different heights along its length.

  3. Aesthetics: Offers a clean, orderly appearance.

  4. Structural efficiency: Generally less efficient than the fan design for longer spans.

  5. Tower height: Typically requires taller towers compared to fan design.

  6. Cable forces: More evenly distributed along the tower height.

Fan Design:

  1. Cable arrangement: Cables radiate from a single point or small area at the top of the tower.

  2. Anchoring: All cables are anchored near the top of the tower.

  3. Aesthetics: Creates a more dramatic, converging visual effect.

  4. Structural efficiency: More efficient for longer spans due to steeper cable angles.

  5. Tower height: Can use shorter towers compared to harp design.

  6. Cable forces: Concentrated at the top of the tower, requiring stronger tower design.

Key differences:

  1. Visual impact: Harp design appears more orderly, while fan design is more dramatic.

  2. Structural efficiency: Fan design is generally more efficient for longer spans.

  3. Tower design: Fan design requires stronger tower tops, while harp design distributes forces more evenly.

  4. Cable length: Fan design typically uses shorter cables overall.

  5. Construction complexity: Harp design can be more complex due to multiple anchor points on the tower.

Both designs have their merits, and the choice between them often depends on factors such as span length, aesthetic preferences, and site-specific conditions. Some bridges even combine elements of both designs for optimal performance and appearance.

What precautions should you take during an electrical storm?

User Avatar

Asked by Wiki User

It is not a good time to be taking a shower or bath. The piping system is a good conduit for electricity and pools of water may attract lightening. Using the telephone and electrical appliances is also not a good idea, the wiring being designed to carry electricity. Close ALL windows and doors. Bring your pets inside. Unplug any electrical things such as toasters, blenders, etc. Turn off the TV and radio! Even cell phones shouldn't be used during an electrical storm. Don't go outside to have a look and stay away from the windows! I actually had a "fireball" come right through my living room window (I was sitting on the couch) and enter my TV (a freak storm with no warning.) The window had no damage nor did the TV. My husband witnessed it and said as the streak passed me my hair shot up. LOL

How do you convert conductivity and temperature to total dissolved solids TDS?

User Avatar

Asked by Wiki User

There is no direct conversion between conductivity, temperature, and total dissolved solids (TDS). Conductivity is often used as a proxy for estimating TDS, especially in water quality monitoring. TDS can be estimated using a conversion factor based on the specific characteristics of the water sample, but it is not a precise conversion. Temperature can affect conductivity readings, so it's essential to measure both parameters accurately when estimating TDS.

What is porosity in relation to groundwater?

User Avatar

Asked by Wiki User

Porosity is the measure of open space within a rock or sediment that allows water to flow through it. It is a key factor in groundwater storage and movement, as rocks with high porosity can hold and transmit more water compared to rocks with low porosity. Understanding porosity is important in assessing groundwater potential in an area.

What produces cross-sectional views?

Would you think that percolation rate be greater in loamy sand thin in silt clay?

User Avatar

Asked by Wiki User

Yes, the percolation rate would generally be greater in loamy sand compared to silt clay. This is because loamy sand has larger particles with higher porosity and permeability, allowing water to move more freely through the soil compared to the fine particles in silt clay which can lead to slower percolation rates.

What is the rising of cold water from deeper layers to replace warmer surface water called?

User Avatar

Asked by Wiki User

This process is called upwelling. Upwelling occurs when winds push surface water away, allowing cold, nutrient-rich water from deeper levels to rise up to the surface. This phenomenon is important for supporting marine ecosystems by bringing nutrients to the surface and supporting the growth of phytoplankton.

Can you convert cubic meter of concrete with density of 2400 kgm3 to metric tons of concrete?

User Avatar

Asked by REYQS

To convert cubic meters to metric tons, you need to multiply by the density.

Cubic meters to metric tons: 1 m^3 of concrete * 2400 kg/m^3 = 2400 kg or 2.4 metric tons.

Therefore, 1 cubic meter of concrete with a density of 2400 kg/m^3 is equal to 2.4 metric tons of concrete.
