Article: Many people choose to order ready-to-use screed mix, which contains additives that slow down the setting so you do not have to work as quickly. If you would prefer to mix your own, try this simple recipe: Select clean sand with a variety of grain sizes. Combine 4 parts sand with 1 part Portland cement. (A standard Type I or Type II A cement is fine.) For greater strength, replace 1 part sand with aggregate. Avoid grain sizes above 10mm (0.4") to reduce cracking. Add water slowly until you can form the mix into a ball, then break it into clumps without water escaping. Professional sometimes make their own dividers using the screed mix itself, but it's much easier to use a timber batten for a DIY project. Use the straightest battens you can find, and cut them to the eventual height of the screed layer. Follow these steps: Lay down about 3 cm (1.2") of screed to keep the battens in place. Wet the batten so you can remove it more easily after screeding. Set the battens down to divide the room into strips 3 to 4 meters (1013 ft) wide. The length of each strip is not important. Use a spirit level to confirm that each batten is level along the top, and level with adjacent battens in the room. Dump screed onto the section farthest from the entrance, using enough to fill about 60 cm (2 ft) length of the strip. Spread it out with a trowel, compacting as you go by "chopping" it down with a screed board (straightedge), and by tamping the edges with a hand tamper. Poor compaction is one of the most common problems with a home screeding job. For best results, rent a vibrating screed board or other compacting tool. Apply each batch of screed within 45 minutes of mixing. Once you have laid enough screed, place a screed board or a very straight piece of lumber over the battens. Push the straightedge across the surface of the screed in a side-to-side sawing motion. Tilt the lumber slightly so the corner forms a cutting edge to make the screed level. Trowel on, compact, and level the screed in stages until the first section is filled, then move on to the next. Once you have two sections filled, remove the batten between them and fill in the gap. Continue until you have screeded the whole floor. If you cannot screed the floor in one day, install day joints at the edge of the screed. . It's a good idea to bull float the screed right away to remove imperfections. Float a second time once the concrete has stopped bleeding and excess water has evaporated (or after you have removed it). For final finishing instructions, refer to your flooring manufacturer or use these suggestions: To create a textured finish, swirl a wood float in an arced motion across the surface. This works well under ceramic tiles and carpets. For a smooth finish, use the same motion with a steel trowel instead, held flat against the surface. This works well under vinyl tiles. . One way to cure the screed is to place it under polyethylene sheeting, sealed at the edges. Leave the screed undisturbed for at least 7 days, or longer if average temperatures fall below 10C (50F) in a 24 hour period. Even after curing, your screed will need time to dry. Avoid vehicle traffic and do not install floor for at least three weeks. As a rough rule of thumb, the screed takes one day to dry for each mm (0.04") of depth. If you are bonding ceramic or stone tiles, terrazzo, or synthetic resin floor to the screed, cut stress relief joints every 56 meters (16.419.7 ft), in straight vertical lines halfway through the screed. You can do this with a trowel now, but it may be easier to align with the tiles if you wait until the screed hardens and cut joints with a saw (within 34 weeks).

Article: Nausea, headaches, dizziness, and muscle soreness are all common symptoms of anxiety. If you regularly experience such discomfort, this may be a sign that you are experiencing excessive anxiety, especially if standard methods for relieving the discomfort are ineffective. The body often manifests psychological strain physically, through symptoms like muscle tension, rapid heartbeat and breathing, trembling, and shortness of breath. Often experiencing such physical tension, especially in the absence of a non-psychological cause, such as vigorous exercise, may be a sign of anxiety. Fidgeting behaviors, such as tapping your hands and feet, grinding your teeth, or clenching your jaw may also be signs of anxiety-related physical tension. Anxiety often has a very noticeable effect on how well you sleep, how much sleep you get, and how energized and alert you feel after sleeping. Oversleeping and insomnia (a sustained problem getting to sleep and staying asleep) are both common anxiety symptoms. Oversleeping intentionally to escape worry, or being kept from sleep by an overly active, worrying mind are both classic problems for sufferers of anxiety. Your digestive system is very sensitive to changes in your physiology, including psychological changes like experiencing anxiety. Anxiety is often associated with frequent feelings of nausea, as well as frequent urination or diarrhea. Many anxiety sufferers experience a frequent or even constant queasy feeling, much like the pit-in-your-stomach sensation associated with a stressful realization. Anxiety often affects what, and how much, you want to eat. If you notice that you are often not hungry, or simply not motivated to eat, this may be a sign of anxiety. Conversely, frequent overeating, especially as a distraction from worry, can also be a manifestation of anxiety.

Article: If someone you're chatting with starts to talk about sex or sexual topics, you should stop talking to them. This includes them talking about or describing sexual acts. In addition, you should be very suspicious of anyone who asks you to talk about sexual acts or requests you to engage in them offline.

What your family situation or living situation is like. If anyone asks whether you are alone, live alone, or are frequently on your on, you should be suspicious. Public chat rooms where there are many people chatting are often safer than private chatrooms. If someone asks you to join them in a private chatroom, you should view this with suspicion.
