How do you design a ventilated improved pit-latrine?
Look at "The design of ventilated improved pit latrines" from Mara, D. Duncan ; UNDP ; Technical Advisory Group (TAG), by the World Bank. The document is available at http://www-wds.worldbank.org/external/default/main?pagePK=64193027&piPK=64187937&theSitePK=523679&menuPK=64187510&searchMenuPK=64187283&siteName=WDS&entityID=000178830_98101903445788 or http://www-wds.worldbank.org/external/default/WDSContentServer/WDSP/IB/2000/04/24/000178830_98101903445788/Rendered/PDF/multi0page.pdf If this doesn't work for you, try a hand grenade.
Is gravel a fine aggregate?
Gravel can be composed of varying sizes of stone, sand, and fine dust, with the coarse stone measuring up to about 2 inches. Large stone is often referred to as ballast or sometimes, pit run. Even larger stone (6" to 24") is called rip-rap. Rip-rap is used to armor the soil to prevent erosion from water runoff. If you are using boulders or rip-rap, then gravel would probably be considered a fine aggregate. But if you are using gravel under a new sidewalk, say, then gravel would be somewhat coarse compared to the sand and fine dust in it.
How is a road built?
It is built using tarmac. First of all come the planning, preliminary surveying and the requirement and impact assessment phases. Inter-urban roads are the most complex. A number of criteria must be considered in the selection of a route, mainly based in the communities and geography to be traversed; areas of natural beauty, animal habitats, what will be the impact on people near to the new road; also, what kind of traffic will the road carry, will earthworks, bridges or tunnels be required and if so, what kind of equipment does the geology dictate; straightness of route must be traded against geographical elevation and the need to avoid too much blasting through solid rock and so forth. Then the route is planned on paper. Provision must be made for adequate drainage, protection of the area flanking the road and possibly the laying in of power for warning signs and lighting. Once the plan receives the requisite local government sign off and approval the work can start. at this stage surveyors will assist the road crew in laying out the route ("staking out"), and provide data for digging trenches and building embankments. Sources of water and material for the road bed must be located. The materials may come from a quarry or more often from a "borrow pit", in the latter case the road crew must ensure that the scar can be repaired back to its original green condition. Once this phase is complete the rock hardcore is laid. Rock is crushed, washed and screen filtered. There are various specifications for permissible lump size. The hardcore is laid incrementally and must be compacted thoroughly. Once the hardcore phase is completed the road can be tarred or concreted and the final road dressing and painting and the installation of safety features and road signs can take place.
What are the best fire bricks for a fire pit?
The best fire bricks for a fire pit are typically made of dense and heat-resistant materials like clay or refractory concrete. These bricks can withstand high temperatures and help retain heat efficiently in the fire pit. It's important to choose bricks specifically designed for use in fire pits to ensure safety and durability.

How can I create a brick fire pit?
To create a brick fire pit, first choose a location that is safe and away from any flammable materials. Then, dig a hole in the ground and line it with bricks to form the base and walls of the fire pit. Use a heat-resistant mortar to secure the bricks in place. Finally, add a metal fire ring or grate to the center of the pit to contain the fire.
How can I build a fire pit using bricks?
To build a fire pit using bricks, first choose a location away from flammable materials. Dig a circular pit about 2 feet deep and line the bottom with gravel for drainage. Arrange bricks in a circle to form the walls of the pit, stacking them securely. Fill any gaps with heat-resistant mortar. Finally, add a metal fire ring or grate to protect the bricks from direct heat.
How can I build a brick fire pit?
To build a brick fire pit, first choose a location away from flammable materials. Dig a hole, line it with gravel, and place bricks in a circle to form the pit. Use mortar to secure the bricks in place. Add a metal fire ring for safety.
How can I make a fire pit with bricks?
To make a fire pit with bricks, first choose a location away from flammable materials. Dig a hole, line it with bricks, leaving space for air flow. Stack more bricks around the perimeter to desired height. Fill the bottom with sand or gravel for drainage. Build a fire on the sand/gravel base. Always monitor the fire and extinguish it completely when done.
How can I create a DIY fire pit using bricks?
To create a DIY fire pit using bricks, first choose a location away from any flammable materials. Dig a hole about 12 inches deep and line the bottom with gravel for drainage. Arrange bricks in a circle to form the pit, making sure they are tightly packed together. Use a level to ensure the bricks are even. Stack additional layers of bricks to reach your desired height. Fill the bottom with sand or gravel for better heat retention. Finally, add a metal fire ring or grate to contain the fire. Remember to always follow local fire regulations and safety precautions when using a fire pit.
What are the best materials and steps to build a durable and stylish brick fire pit for my backyard?
The best materials for building a durable and stylish brick fire pit are fire-rated bricks, fireproof mortar, a metal fire ring, and a grate.
